: Core support a/c holes
TOM BARKLEY Jul 5th, 06, 11:01 PM Does anyone have close up pics of a 69 a/c core support where the holes come thru for the a/c lines? I have an a/c car and most parts are missing and I don't see any holes in the core support.The guy I got the car from said it had no front clip when he got it. So i'm thinking it is a non a/c core support? Close up pics would be greatly appreciated. Thx
BlackoutSteve Jul 6th, 06, 01:10 AM I don't think you see any holes because I'm pretty sure there aren't any!
According to my 1969 AIM, C60-D4, 5, 8 & 9, it shows with reasonable clarity, both lines routed underneath the core support and not through it. :)
JimM Jul 6th, 06, 05:34 AM I was just eye-balling click's fact air rs last night, the hoses pass under the core support.
Unreal Jul 6th, 06, 08:39 AM The only extra holes in the core support are for the clips that hold the core support to hood seal. I forget if the attachment holes for the side baffles use existing holes or if you have to drill them.
There's an aluminum tube that connects to the condenser on the driver side and runs along the bottom of the condesner to the passenger side. I think it has a clip or two to attach it to the core support.
jet_car2000 Jul 6th, 06, 08:47 AM heres a picture click posted in another thread of Click's car where the line goes thru under the battery
TJS69 Jul 6th, 06, 12:41 PM Are you talking about the holes, with well nuts, that mount the condensor ?

The baffles use existing holes with a bolt and J-nut. In fact, they are the same holes that convertibles use (or would use) to mount the dampers.

car_habit Jul 6th, 06, 10:23 PM On both of my 69's with factory air, one SB one BB, the hoses are routed under the core support. Unless you have an aftermarket, dealer installed, or some other under-dash type unit, that is how they should be.
I believe the hoses are passed through the core support on a 68 to 74 Nova, if that's where your A/C parts came from. They may fit if you drill holes, but if you are looking for correctness get the correct hose kit.
Rick First Gen is selling repoped A/C hoses for small block cars. They sell a whole kit that looks pretty close to factory routing. Check this link;

TOM BARKLEY Jul 6th, 06, 10:37 PM Thanks Guys ... It's a big block A/c Car and everything is missing other than the firewall box with a big hole in it . It was an old drag car and everything was removed. The engine suitcase was in the trunk and most underdash stuff is there. just no underhood stuff. Anybody make Big Block correct repro lines? or other parts?
car_habit Jul 7th, 06, 04:21 PM I have never run across the correct lines for a BB for sale anywhere new, good luck.
If you can find the fittings, (V8 Firebird fittings are the same at the firewall), any A/C shop can make up a set for you, although they probably won’t be able to make them look like the factory crimps. The SB lines are the same except for that one fitting at the POV on the evaporator housing, so they could be modified to work.
Used compressor mounting brackets are available from Rick’s First Gen, D&R Classics, (many other used Camaro parts dealers), and on eBay from time to time. 69 BB compressor mounting brackets are unique to 69, and 70, ($$$), later model parts will work, if you just looking to build a functional system.
The most critical and often overlooked parts are the radiator, and lower shield. The lower shield attaches to the core support and to the sub-frame to direct air-flow through the radiator, not around it. It is made of pure un-obtainium, and almost always was removed and pitched at some point in the cars history. Several companies (DSE for one) sell an aluminum lower dress up kit that could be used to perform the same function. The correct radiator is the Harrison 4 core curved neck model. There are some repops that are functional equivalents but the correct repops are expensive. The curved neck is needed to safely route the upper hose away from the A/C compressor clutch.
I was thinking about swapping over my SB car to a BB at one time, until I found out the cost, and trouble associated with making the A/C look correct and function. I found the only substitute for cubic inches, is the cubic $$$ it takes to get them ;<)
TOM BARKLEY Jul 7th, 06, 11:05 PM Habit... I thought old air products in TX might make the big block lines? I have the correct radiator and shroud and a few of the compressor brkts. no that lower baffle is missing. Some late model trucks use a similar plastic piesce I might try to rework one. It's a long road to resurect and old drag car.
Unreal Jul 8th, 06, 01:47 PM I remember a discussion a several years ago about that lower shroud. I thought the concensus was that while it is shown in the AIM, it never made it into production (not unlike the B/B driver smog hose bracket)
As for the replacement parts, I got the correct evaporator core (bends to the inside) and all the hoses from Old Air products. They did not have a template for the liquid line on a b/b, so I mocked one up using a small block one, a piece of copper tubing and an extra piece of hose. They lost it, and I did not have anything to resend them. They made up set with extra length and did not attach the hairpin piece. I was planning to cut it to length and send it back to them for crimping. But I was able to find a local refrigerated trailer repair shop that had the same crimp pattern, so I did not have to send it back. That was several years ago, so they may have the correct template by now. They did not want to use mine as the template, as it was not an original.
Unreal Jul 8th, 06, 01:52 PM As for the crimps, I no longer have an original to compare to, but going from memory (a dangerous thing at my age) the originals were crimped radially, and all the crimpers I have seen (including Old Air Products') crimped linearly. So originals have crimp rings around the fitting, and the new ones have crimps that parallel the fitting.
car_habit Jul 8th, 06, 09:02 PM I remember a discussion a several years ago about that lower shroud. I thought the concensus was that while it is shown in the AIM, it never made it into production (not unlike the B/B driver smog hose bracket)
That would explain why I have never seen one...and I thought it was just MIA on my BB car.
BlackoutSteve Jul 8th, 06, 09:24 PM They did actually exist, but for some reason, far less are "out there" compared to BB-A/C compresser brackets for example. (As only BB with A/C were supposed to have them.)

"Mark X22" has one, and has reproduced one also. Perhaps you can contact him and ask if he is taking orders.
Hey Mark. :thumbsup:
car_habit Jul 9th, 06, 03:39 PM My brother had a 68 Firebird 400 with A/C that had a similar lower shield installed, but it was not the same as the one drawn in the 69 AIM. We figured out that due to differences in the front sheet metal it wouldn’t work on my Camaro, or I would have had one made up back then. I have seen several of the FB shields on eBay, but I have never run across the one in the AIM.
I have looked at many cars, at shows and such, and never even seen the one drawn in the AIM. On really hot days my BB Camaro will get hot, (not over heat just really hot), when cruising with the A/C on. If Mark X22 has reproduced a BB lower shield, I’ll be first in line for one. If he needs some reason to make some up, maybe we can give him one…
BlackoutSteve Jul 9th, 06, 06:43 PM I'm already in line for one. :thumbsup: (I hope the shipping doesn't kill me!)
TOM BARKLEY Jul 9th, 06, 07:23 PM Put me in line for a shield too!!
