The VA bracket has an OEM look.

Ha Ha!!!

Wow, what a blast from the past! Actually, it's very timely. I took my ac belt off years ago when drag racing, and I lost it. I couldn't remember what size it was until I saw the post you linked. In that writeup I included the belt size - 59.5"!

Thank you sir! My racing days are all done, so I am making the Bird a little bit more comfy.

Yeah, that CAA bracket still seems better suited to mount a 50 cal Browning M2.

That’s a great thread! Haha

Sounds like there's a few ways to go but pro6ten compressor and parallel flow condenser seems the easiest to upgrade.

I like the newer sanden compressors, I've used quite a few.

Yeah they take less HP to turn but that comes with a price. They also don't pump as much as the old A6 does.

A proper working A6 is one hell of a freon pumper, the internals are much larger, they simply move more freon than any sanden will.

The sanden will get the job done though and is a nice way to go if you don't have a good working A6

A note. The pro6ten compressor comes filled with oil compatible with R134 Freon. If you decide to use R12 you need to drain it and put in R12 compatible oil.

Finished product was comfortable as long as it was on recirculate and max fan. It spent every summer on max high recirculate. Main problem was air output - or the lack of. At least a total of four different fans were tried and I went back and double sealed all the joints and re-foamed the diverter doors. Again a comfortable system, but I haven't been in any early GTO that had good air output out the vents.

On my blue '67 GTO that never had AC I went with a Vintage Air Mark IV system. I told the rep that I wanted to oversize the condenser and compressor and his answer was simply "trust me, the standard ones are great". I installed the system six years ago and it is still freezing me out of the car. Unlike the original system that needed to stay on max, I'm reaching down and turning down the fan speed and cranking up the temp within five minutes even on 100°+ days.

Oh, and weight. I weighed the complete Vintage Air system including the cans of Freon and everything weighed 54.78 pounds. The old A6 compressor by itself weighs 33.36 pounds.

I chose the Mark IV under dash unit because my original heater was working fine.

Great information. I like the Mark IV 'suitcase' system because it looks like the factory AC in my old '64 Galaxie---which looks like a lot of factory and 'add-on' AC systems of the '60's and early '70's. It's attractive, 'period correct' and looks like it belongs there, instead of something from decades after the car was built. If I pull the trigger it'll be a Mark IV.

Moving in that direction with the Mk IV
I'm using the Pro6Ten compressor to utilize the factory mounting brackets.
