The stock AC compressor and parts were removed years back. I'm thinking about eventually putting a stock looking unit back into the Trans Am (79). I'm a bit curious...and was wondering how many of you don't have "air" in your "hot rods."

I know that Mike Boes has what appears to be a Vintage Air AC system in his Pontiac--what about the rest of you guys? Any AC?

(I'm not sure my car with AC would even work with the cam I have...it might be too rough for it.)

I have it in my xe284 462, no problem. Aftermarket old air products kit. My 66 c10 is factory air but was missing the compressor and brackets. Condensor and drier were beat up, so i got direct fit ones from old air products and a sanden compressor and brackets, gonna paint it black to blend in. Any more, unless it's a very original car, im putting in a/c and overdrive.

My 77 T/A has A/C but the compressor is out of the car ( its a big sucker too ). I'm not sure if all the parts are there to get it going, but I would like to have it some day.

My original A/C is still in the car,and it works. I don't really use it though. I do turn it on a few times during the season while driving just to circulate the freon/oil.

Mine is an AC car but was removed prior to my purchase. I plan on putting a Vintage Air system in the car to take advantage of current technology but keeping the vintage look as much as possible. And it sure gets hot here in VA!

The Previous owner replaced the compressor with a sankyo aluminum and a beefy bracket that uses 3 bolt holes on the front of the cyl head. The rest of the POA type system looks factory.

I have all the original components and brackets but the 134a will require new non-contaminated parts.

All of this is down the road...in the future...just trying to get my "ducks in a row."

It's too darn hot to drive anyway down here without Air.

Ester oil is compatable with 12 and 134 and is used on the conversions. I used it for years. No failure's that i know of. The dryer is always replaced. Auto manufacturers went with a darker, more reflective tint of the glass because 134 is slightly less efficient than 12. The biggest problem i had was with the conversion fittings. Some were poor fit and quality and would leak. And dont over tighten.

My 70 LeMans is a AC car but the PO removed the compressor and hoses. Haven't decided to go with Vintage Air or try and get my existing system working.

not my car

If you have the inside mixerbox, firewall part, controls, etc...just get a sanden compressor and bracket, a new drier, and condenser if yours is beat.

The new sanden design has a crankcase that has oil in it, like the ol A 6. The A 6 is a good compressor.
Synthetic PAG oil is compatible with r 12 or r134a and is the best choice for oil in todays AC systems.
I use it exclusivly in all my repairs as it mixes matches with anything.
A new drier is allways a good Idea and the r134a compatibles are easy to get.
If it were mine I would try and keep it factory looking with an A 6 .
If you have a POA system, they really work well, when the POA is functioning and there is a way to adjust it to optimize it with R 134a.
The adjustment is in the end of the valve that goes toward the compressor (relative with flow that is).
The one thing I would highly recommend over all is to get a real good Paralell Flow type condenser to replace your old tube fin job.
Fin/tube are pretty inneficient, the paralell flows are better hands down. In the Florida heat and humidity...your system really eeds to be up to snuff.
If you like I can dig up a link for the POA adjustment.
If you have a CCOT type system .....never mind.

I still have the original A6 compressor that came with the car. It seems to me the problem it developed was a leaking seal. It should be rebuildable. Not sure I'm capable of doing it though.

There are drop in R-12 subs you can use. Hot Shot is one with no oil change. With 134A you must get 95% of the oil out. The seals on your compressor should be changed being 34 years old.

Those big compressors and brackets weigh near as much as an iron intake.
