Air Conditioning Compressor Bracket/Belt Pulleys The Same? For both the Vette & F-Body? I'm converting from Camaro accessories to Vette accessories. Will the Camaro air compressor bracket be out of alignment with the Vette dampner, etc...? Can it be modified? Thanks, Ed

Re: Air Conditioning Compressor Bracket/Belt Pulleys The Same? You'll have to get the Vette bracket. There's too much difference to adjust for. It looks like about an inch difference between the two.

Re: Air Conditioning Compressor Bracket/Belt Pulleys The Same? John. Where does the 'vette compressor install. I was unable to use the f-body location and was a little leary of using the f-body compressor on my Astro AWD swap so I mounted the Astro compressor down where the f-body had the alternator and figured if the Astro compressor failed for some reason I would install the f-body on a fabricated bracket hence my question. It would be nice to use a stock bracket for mounting.
Thanks for the reply.

Re: Air Conditioning Compressor Bracket/Belt Pulleys The Same? During the install of my 99 F-body LS1 in my 66 Vette I had to move the alt from low to high left so I used the Vette bracket. I had to grind a little off the bracket to get the stock F-body p/s pump to fit. I also had to make a couple small adapters to get the F-body alt to fit the Vette bracket. The F-body crank pulley is .748" farther FORWARD than the Vette pulley so I made a spacer to mount between the head and the bracket. I also moved the a/c compressor from low to high right by using a custom bracket mounting a Sanden compressor rather than the stock one. The whole mess is driven by a single serpentine belt whereas the F-body and Vette both use a separate narrow belt for the a/c compressor. I don't know for sure if the Vette and F-body compressors and mounting brackets are the same but I doubt it because of the difference in the crank pulleys.

Re: Air Conditioning Compressor Bracket/Belt Pulleys The Same? So the crank pulley's are different between the two cars. The 'vette being about 3/4" shorter. That being the case, I guess another custom bracket is in order as the 'vette bracket would not allow the compressor pulleys to align.
I built custom brackets for all the accessories. Stock f-body PS pump mounted to passenger side head without the reservoir (a la stock car with remote reservoir). Stock f-body alternator mounted high to driver's head and the Astro compressor mounted low. I constructed the brackets from 6061 aluminum blocks (3" thick). The machine work was done with electric hand tools. I had to use 2 idler pulleys and 1 tension pulley from a 2.2 liter GM. It works well. The only problem was stopping the belt squeal which was solved by the 2.2 tension pulley mounted between the alternator and AC compressor.
