Ac for chevelle!
I used the Kwik bracket on my cutlass, but if your engine is far enough forward, or you notch your crossmember, this one might work.

Do a search here for variable displacement compressors. It will work but at reduced efficiency. They operate at different pressures.
I'm using the kwik brackets and a sanden 508 compressor. When used with vette accessories, it creates symmetry on the front accessory drive and doesn't look too bad IMO.
..actually ordering my vintage air stuff today, $1100 on the button (plus shipping), looking forward to it.

I like the Street and Performance passenger side low A/C bracket. It puts the compressor down low, like the OEM compressor. I just do not like the look of the compressor sitting up on top of the engine. No OEM compressor will fit on the Chevelle unless you are willing to notch the crossmember to clear it.
If you look real close in the following pic, you will see the Sanden compressor hiding down there.

This pic shows a stock tensioner, but you will need to use a Katech or similar manual tensioner to prevent belt slip. I just had not put mine on yet. This is just a bunch of stuff to drive on a single belt!

Not true John. If you move the engine foward a bit they will fit F-body anyway. At least it did on mine but I am running manifolds not headers. I think with all of the kits that include mounts and headers your statement is true.

Rocky,
You are correct. It also helps to be using a set of F body accessories as well.
I screwed around with mine trying to get the OEM compressor to fit with the Corvette accessories and finally just gave up. I had to move the engine so far forward that I would have had to do major oil pan modifications and the headers would have been a pain. I use the S&P brackets on both the wagon and the 65 Corvette, and I really do like them. I am not sure that I wanted to use the OEM compressor with the VA system, as they reccomended against it.

I have been doing some reading on A/C compressors lately and it looks like all of the f-body compressors were variable displacement which will lose efficiency when used with the VA setup. The truck compressors all seem to be fixed displacement which should work just fine.
I have a 07 truck comp on dads chevelle with a vintage air kit.
On power tour in 97 degree heat we didn't need the fan all the way up to be more than comfortable.
One thing when you order the kit from vintage make sure you get straight fittings for the hoses to the comp. They sent me 150 degree ones that would not even bolt to the comp.
Getting the comp to fit didn't require notching the crossmember either. The trans moved fwd less than 1/4".
I moved the mount pads on the crossmember fwd and moved the mounts on the edelbrock swap brackets back so the bottom bolt on the stock motor mount shared a bolt with the edelbrock plates.
Also notched the back part of the comp bracket to clear the edelbrock plate.
Don't see how a 2 wire comp can be varible displacment if it is unless they have a valve changing pressure to the pump.
I am very happy with the performance of the kit.

They have a mechanical valve built into the side of the v7 (f-body) compressor which somehow changes the displacement. Found a few articles about it online but I havent taken one apart so I don`t fully understand how it works.
