Wow this is great! Thanks guys for contributing to this thread and adding in links to the previous threads( Jim, Bob, Mark). The links from MarkC are excellent. The pages from the TSB are very interesting. To answer Bob's question to me about the seal across the top of the core support- I have a late build 68 SS L34 with factory A/C (3rd week July and Norwood plant). I think it has the original core support and it has the RH fender baffle but not the left half fender baffle. The left fender was replaced at some point with an NOS fender ( it still has remnants of the GM part number sticker on the inside). So I am guessing the car was wrecked at some point and the LH fender baffle may also have been damaged. My car also under went a restoration at some point about 8-12 years ago (I have only had it about 2 years now). The top of my core support has the dimples but no holes for the seal clips. That seal you mention was not on the car when I got it, but I plan to add it as I work through the engine compartment details.
Mark C's link ( topic=1726) has raised another important question about A/C parts. Note the pictures of cars on reply # 23 March 21, 2007. Note Picture 2 of the Norwood Camaro with factory A/C. Now note the A/C manifold muffler design. According to the AIM, that design for the muffler was used on the L6 engine and not the V8 engine ( the suction side goes up over the compressor on the manifold design used for V8 engines). However, I have noticed over the years there are a few V8 cars with factory A/C that use the muffler/ manifold style shown in this picture (the suction side pipe wraps more under the compressor on the L6 design type). Do you guys know if both manifold styles are correct for V8 cars or if the style shown in this picture is NOT correct for V8 cars?
Getting back to the 1968 fender baffle issue - I am getting depressed. I can't seem to find one anywhere. But man, I have sure learned a lot from Jim, Bob and Mark C, thanks very much. This Team Camaro Forum is fantastic!
