when resealing the under dash heater box are you guys actualy disassembling the metal unit to put the seals in? or are there no seals inside to replace?
thx scott

Scott,
No one may be answering your question because they do not understand what you are asking. I am not sure either? Also, do you have A/C? The heat box is Fiberglass. There are metal doors inside. And, Yes, there are seals inside. Unfortunately, all the seal kits suck. There is much already written about this on this website. If you take the box apart, which is NOT an easy task if you have a/c, assume that there is NO replacement parts. That attitude could save you a lot of aggravation later.
Good Luck. Post a picture would help also.

oh sorry ill explain, inside the car(67) under the dash is a metal heater box that contains the heater core and has cables that control flapper valves for defrost, heat and vent modes (non-ac car) i did a search and saw were someone cut the spotwelds to disassemble the box to possible replace seals inside ? i dont see any seals to replace inside? they could just be already gone? this box is metal and bolts to the fire wall with studs that on the eng side of the fire wall mount the metal box with the fan motor mounted too under the pass side fender.
thx scott

Scott: I don't think you have a 67 heater box although mine is an A/C car so it could be different. The box on my 67 was not made of metal. It is a black composite plastic. You should be able to remove it by disconnecting the cables and removing the screws and nuts that hold it. Inside should be your heater core and a couple baffels (flappers). Does it look like this?

POST SOME PICTURES.
There really were not seals, they were RUBBER and were part of the doors. There were some seals.. At inlet/outlet tubes, under the core and at firewall. You can restore the rubber by soaking in silicone sometimes. There are also metal doors that you can clean up also with NO rubber. They were not painted from the factory, but if you are afraid of them corroding, you can paint them anyway. No one sees them once you have the box rebuild.

Like I said earlier, the kits suck and most of the time they don't give you enough parts to fix your box, nor do they give you the right size parts to fix your box. You will probably find that if you post your box, we can tell you how to restore it without the "kits". Order the kit anyway, you will most likely use 1 or 2 parts.

I took these picutres to help show where they want you to put these gaskets and how they compare. If yours is really bad, you will have to just make do. But, if your original are not to bad, you will find they work just fine.
Good Luck!!

Fiberglass heater box? Hmmm.... maybe mine isn't a 67 heater box either.

Scott, to answer your question, I did buy one of those reproduction seal kits. Yes, they do suck.... but I did a little trimming here and there to the foam pieces and I think it seals fairly well now. If nothing else it doesn't clang when I move the defrost or temp sliders back and forth. And not a lick of hot air when the lever is on the "cold" side, so I think the heater controls are doing their job well now. I didn't disassemble the unit, but that did make it a little tougher to try and position the foam pieces, after I slathered a bunch of glue on them.

Good luck.

I've had two 67's that had a metal heater box, but I never tried to disassemble one.

Scott,

I am not sure what is being talked about here. Daral has a nice picture of an ORIGINAL heat box above (I assure you, they were not metal.) My pictures show the METAL that was inside, not counting the metal heater core and brackets (which have been shown on another thread). Maybe you can show a picture of yours. Email me the picture and I will post if for you, if you do not know how. Like Aaron said, you can make the suckie Kits work if you have to. They are better than nothing. But, don't give up on the old ones without trying.

Mine is out of the car, just pulled it, completely original and entirely metal (no A/C). Doesn't look at all like the photos above.

Maybe it was a change from metal to plastic at some point in the production?

Can someone post a picture of their metal heat box??

hey all thx for the replys
my 67 is a very early model maybe in the first 10% built in 67, the heater box is diffenitly metal!!:yes: spot welded togethere,non ac, its on my work bench and looks nothing like the pics posted above, ill post a pic tommorrow.
thx scott

Yup, sounds just like mine. Mine is a Jan 67 car.

Mine is an O1B (2nd week of January) and as you can see from the pics above it does not have a metal heater box. Could the difference be A/C or non-A/C? Mine is a factory A/C car. Could the difference be between Norwood and LA cars?

mine is a nowood car ill get the vin and take a pic of the box tommorrow i think i remember my car was manufactored in oct of 66 ill check
thx for the info
scott

I think it's gonna come down to A/C = plastic and no A/C = metal. Just my feeling at this point.

i think your problee right ac= plastic, non ac= metal
on another note is there a ref source that matches the cars serial number to a date and year? not calender year? my ser # 178770 some 67 models where manufactored in 66 so were is the cut off?
thx scott

I can't wait to see the picture.

Yup, just like mine. This one in the picture shows one of the plastic ducts attached also.

Those are much different than mine. I agree with Scott, it has to be the difference between an A/C car and non-A/C. Has CRG done any research on this?

hi all, hers the pics of my heater box for a 67 non ac! i called a camaro guy last night and he said the difference is in the ac verses non ac, at one time this guy had 30 first gens till the city zoning caught up with him, so he parted them all out into storage and sells parts. i have bought a few things from him and trust his info.
thx for all the help:hurray:

also looking at the ebay pics you can see there is a lot of variation in the boxs that are listed for 67 that i see?

anyword on my above serial number tied to manufactoring month and date question?

I've been watching this thread and there seems to be confusion about AC vs non-AC cars. Metal boxes were for non AC cars. I have 4 in stock for spares. Also 1 in my 67, one in my 68, one a 69 and one in a 68 parts car. I've had these and others for over 27years.

Tom,

thanks for showing the box. Seeing the first one you posted reminded me that I had seen them with rust on them. I think most of us already knew the visual difference between the a/c vs NON a/c. I had just forgot that they were metal.

I have a 69 heater box with A/C. I also bought a seal kit which I agree sucks. I was able to use the new seal to seal the evaporator to the case. My flaps have the original rubber around them and I am able to reuse those as well as the original rubber that surrounds the evaporator pipes. I'm trying to figure out where else the seals go inside the box. There wasn't much left of the original ones when I took it apart and I can't remember where they go. I also want to make sure the flaps (doors) are all positioned correctly before a put it back together. Does anyone have any pictures?

thanks

I suspect they used non-metal boxes for AC cars because of the very cold air inside the box during cooling. A metal box would allow condensation to form on it and drip on to the floor. My '67 AC car (built the 5th week in Dec '66) has a non-metalic plenum. Leaks terribly.

Took her for a long spin this morning. Temps in the 30's. Passenger nearly froze from the cold outside air coming in from behind this box. Oh yeah, wind was 20 - 30 mph out of the north this morning.

Guess I need to pull the box and try to seal better around the firewall. Need to work on the defrost damper anyway.

Here is a scan of a sheet that came with some seals I bought a while back, I don't remember the vendor. Better find someone with small hands to put them in.
