Ive looked at my AIM and Chassis books and cannot find any reference to this rubber grommet type thing that was between the inner fender and radiator support on the flat surface behind my washer bottle on passenger side. It has 3 metal tabs that screw to the flat area hold it in place with a large (apox. 1") hole thru the flat metal area under it.
Its not for my AC hoses, so a beer to the first one to correctly name this piece. graemlins/thumbsup.gif

Its the thingamajig that holds the watsamacallit to the dohickey. everybody knows that :rolleyes: And you call yourself an expert redface.gif No thanks just glad to help graemlins/waving.gif

I thought it was a muffler bearing, or an end-cap for the custom 24" underchromed rhubarb. Perhaps the pop-top to a cocktail shaker? Hmmmmm... ;)

Click, was this mounted on the rad. support or inner fender liner? What do you mean flat surface? Being your car is an RS, I assume you're referring to the inner fender liner behind the washer bottle bracket..

That is a blinker fluid drain plug grommet graemlins/clonk.gif

It's a balljoint boot for a 1927 Buick.

You guys are a hoot... muffler bearings, fluid drain :D
Its behind the windshield washer bucket and battery tray, on the pass side (RS) on the horizontal flat metal that lies between the inner fender round part, and the rad. support. There had to be something that goes thru it but Im stumped??
Maybe I should try to get a pic of that area but its so crowded not sure I can get a good one. Thought for sure JohnZ or a few others would recognize that right away. graemlins/thumbsup.gif

I would say it is something for the 69 RS option. I don't recognize it as a 67-68 part. Could it be a grommet for the parking light wiring? It's only on the passenger side?

Passenger side only and much to big for wiring, definately not parking lights wires tho. ??
:D

hhhhmmmmm??? I think its for an A/C line grommet, to pass thru the inner fender to the condenser??? I seen one of those on my duece once.Just a guess :rolleyes:

(Said by Arnold)

No, no, it's a cappucino maker. That's what it is. :D

Or,

It's the pass-thru for the RS headlight washer lines option.

Rick.

Jim - I was thinking it looked like this thing a college girlfriend used for birth control but it didn't have a hole in the center of it!! :eek:

I think it's A/C related but didn't see anything in the AIM that looks close. Was it actually bolted in place or just sitting wedged between the core support and inner fender? A pic would really help, I've gone through the RS and A/C pages of the AIM and can't find anything...

HA I got it!! its the grommet for the heater core.The three little tabs with the hole bolt to the A/C suit case. graemlins/hurray.gif

I dont recognize that. It must be related to the A/C system somehow.

It only has those 3 screws that hold it in place. All the a/c lines go in front of the radiator and then around the engine side of the battery and up to the filter box that bolts to the inner fender. When I was installing my accuator splash shields and laying there looked up and saw that hole,then behind the battery were the 3 screws holding it in place, it looked factory installed, clean punched hole. I have to remove the battery unless someone comes up with it. The AIM sure didnt show me anything went thru there either. A real mystery.

That's an A/C line grommet............isn't it?

The Assembly Manual doesnt show any a/c hoses over there. The hose is on the engine side of the battery not behind it where this hole and grommet are.
?? :eek:

click does it have something to do with the RS linkages or assemblies (accuators)? Am I getting close.I dont have an AIM 69 book,just 67.The book sometimes wont show small parts unless its a sub assembly(i think)

What's the build date of your car? I think early production cars had the A/C liquid line hose run from the condensor, up under the fenderliner, through the grommet then to the drier. It may then have been redesigned to simply let the line pass behind the battery to the drier.At one point in your car's life, the line may have been replaced and simply re-routed.
I bought an early LM1 with A/C Camaro that had the front sheetmetal taken apart and I found the exact same grommet thing in a box in the trunk.

Panther that might be it, its an Oct 4th week build car so perhaps early ones routed that way. I know the hoses were replace before me so guess maybe the new hoses went the other direction. The mechanic that worked on it tried to route a/c hose thru that grommet but there was no way it would work with the length and bend in the hose. That why we wondered if there was some other option that used it that Im not aware of.
I will get pics this weekend of it in place. My first guess was a/c but when it didnt fit, kinda deflated that idea but a design change would explain it. Wonder if JohnZ has an idea?

It's power drain tap. The guys from the Ford factory snuck over the Camaro line durring build up and installed these on many Camaros. Power loss was a mystery for many years until these devices were dicovered. Your Camaro should run alot faster now that it has been removed. :rolleyes:

Joe

I think you guys are on the right track with the A/C. It is not for the RS actuators or linkages,

Ok all you super sluths, here is the location and I set the grommet in place for the pic. It has the letters AB printed on the rubber portion. The bottom with the screw tabs is all metal but the rubber was molded over it too.
Are we finding agreement yet on its use? Im leaning toward an origilan AC hose route that was changed. Id love to hear JohnZ pipe in on this. Dont ya love a good mystery?

http://www.brainerd.net/~knudsen/69RS/AChoseGrommet.jpg

I positively do not have that on my RS car nor do I have A/C. :D I think my car was built in the same timeframe as yours. (11B)

Looks like a condenser drain sealing grommet.

It's a rodent escape hole. That way they won't die in your engine compartment and smell bad. GM thought of everything.

Found it! looking on the left side of the warp drive core on enterprise C, you will see the same thing was used as a peep hole into the core.Very rare option. only available on warp drive models. graemlins/waving.gif

Jim, is that looking down? The hole in the middle of it passes straight down towards the ground?
The only thing I can come up with is some sort of drain, but that's one big hole and fancy grommet for a drain.
:confused:

Yep Joe it goes straight down, and the rubber part has a built in curve to it, not just a simple straight rubber upside to it, so obviously something came thru there at an angle, then. Thinking Panther was on to it if we can convirm other early LA cars with A/C might have it too? Still hoping JohnZ can pick up on it. Really a brain teaser, but not a warp coil drain either. :D

Dunno - sure looks like some sort of protective grommet for an A/C hose; maybe Mark C. can figure it out - he really knows the A/C system. graemlins/clonk.gif

Ok guys, I got an email from Mark C with now a need to see a 68 AIM which I dont have, does anyone have their 68 AIM handy and can scan the pages Mark referes to here and email them to me please?
Mark quotes now:

Nope, I can’t find it in any of my parts manuals, or other sources. Might try looking in a 68 AIM under C60 as the 69 AIM that has been copied is a pretty late revision so if there was a routing change for the A/C hose the page was replaced and or redrawn before the AIM was copied.

On page C60 D8 and D9 (Hose Routing) of the 69 AIM the very first revision, on 9-5-68 under ECO 96293 the drawing revision block says “Sleeve Removed”. Can’t tell where it was removed from though. It also indicates the routing was changed but we would need an earlier revision to see the changes. On page B2 Air conditioning Receiver & Dehyd. there is a circular item on the drawing in the inner fender right under the dehydrator and behind the battery tray that could be the sleeve if it was for the condenser to dehydrator hose.

Best guess is that it was a pain in the butt to thread the hose thru the grommet at the plant. That and the fact that the 68 style dehydrator brackets changed sometime between the two years so that instead of the dehydrator being mounted straight up and down in 68 to being angled in towards the engine at the top in 69 might be due to this routing change.

Thanks to Mark for the input, lets end this mystery with the 68AIM anyone?


graemlins/thumbsup.gif

Nope, not shown in the 68 AIM.
The washer bottle was moved to the passenger side in 69, so it may have been needed to clear that. The 68 w/bottle is on the driver side inner fender.

Washer bottle only went to the passanger fender on RS cars...

68 was a different design being the compressor was mounted on the RH side so both hoses came to and from the condensor on the RH side. Think about this: 67's used a grommet VERY similar to your's but had 2 holes through it for both A/C hoses and was mounted very close to where your's is and used the same tab-hold-down system.
Put this one down in the books..We're done..Case closed..When do I get my beer? smile.gif

graemlins/beers.gif graemlins/beers.gif graemlins/beers.gif graemlins/beers.gif graemlins/beers.gif graemlins/beers.gif how about a six pack for the weekend? graemlins/thumbsup.gif

Id like to have a copy of those pages from the AIM that mark mentioned so my AIM is more current for my car. Anyone see what he mentioned in theirs?

It's definitely a grommet for the AC condensor hose, although mine has 4 scews and 2 grommet holes. Is this a 6 or an 8 cyl.?

John Doyle, its my 350 RS , still hope someone has those pages from 68 AIM they can scan and email to me?
graemlins/thumbsup.gif

jim, i have a '68 AIM, and i just read through C60, and couldn't find any illustration of such a piece. under "reciever dehydrator", i don't see anything either. it appears the hoses run along the inside edge of the inner fender. crazy deal. if there is a section i can scan for you i'll be more than happy to, but i'm just not sure what picture will help you. smoebody has got to have some "hard evidence" on this one, good luck, someday we may even know its name graemlins/thumbsup.gif

Jim take a look at page 46 of Rick's online catalog. Its not a 3 hole one but the 2 hole one instead.
http://www.rickscamaros.com/online-store/scstore/graphics/ac-35.jpg

Seals heater core tube to evaporator case. High quality reproduction in molded rubber with imbedded metal flange as original.

Whatever it is, you could probably sell it on ebay for thousands of dollars! Just use some of the creative thoughts that have already been submitted for your marketing prose.

In the meantime, my guess is that it is probably a vortex generator that attracts women and increases gas mileage by 30%. I must be right because I saw a similar item in a J.C. Whitney catalogue circa 1972. I think it was near the cable operated exhaust cut-out that would make your puny six sound like a manly V-8 (and help you attract women.)

Jim :cool:

Jeff thats close but no cigar, I saw that in the catalog but that is on the evap. box , this is down behind the battery tray. Very similar obviously but 2 different parts.

68rs thanks for looking, did you read any of Mark's findings about changes? Not sure which revision your AIM is, see if any of Marks comments are evident in your AIM,
here is his quote again

It also indicates the routing was changed but we would need an earlier revision to see the changes. On page B2 Air conditioning Receiver & Dehyd. there is a circular item on the drawing in the inner fender right under the dehydrator and behind the battery tray that could be the sleeve if it was for the condenser to dehydrator hose.

If we had an early 68 AIM that might help us pin this down too.
Thanks for the efforts, Id like to have copies of this for others that might run into it someday.
graemlins/thumbsup.gif

click, no problem. yes, i checked that section of my AIM, but all it had for revisions were a couple of changes for attachment of the rec.-dehyd, and torque specs. last revision was dated 1-11-68. the doc. was orginally printed 5-67. so i dont know what to think about that. maybe a leter '68 version would help? at any rate, good luck on the search graemlins/thumbsup.gif

I thought that is was for the magnet. The chick magnet!

You know, now I remember...I saw a part like that once before...a long time ago, at a little shop just outside of Roswell, New Mexico. The government claimed it was from a "weather baloon"... :eek:

Once I saw the picture of the grommet in place, I could clearly see that is where you screw in the light bulb. Remember the risk of fire, nothing bigger than 75 watt, please.

(I think my 69 is October with a/c... I'll go take a peek this evening to see if we match.)
