I installed a after market air conditioning system in the 73 about 2 yrs ago. I turned it on yesterday & warm air only so I checked everything & determined it was low on freon. So I tried to pull a vacuum & the best it would do was -20...so I determined it had a leak. I then added some freon & a young men who works for me heard the leak right away ( I didn't hear anything Embarrassed) The condenser has a small pin hole. I then called Classic Air where I purchased it from & proceeded to order a new one. He had me in there system & stated it was still under warranty & they will ship on out right away NO CHARGE with a return label for the defective condenser. So anyone that wants to up grade there air conditioning or just add one ..CLASSIC AIR is the place to go http://www.classicautoair.com/ 
If you are a novice at this they are very helpful too.  It's much easier to install a new air conditioning system than than fool around with the old factor unit that never worked that good anyway.

A/C in a vette back then was marginal. And R12 was a good refrigerant back in the day. Converting a factory system to 134a is a waste of money.

I don't think so & I won't take it out until I get the new one to prevent moister from wrecking the dryer. I'll look it over good when I get it out. This isn't the first condenser I've seen go bad.

Jack, my compressor went out right after I purchased the vette. Help me if I'm off on this. Your saying the best thing I could do would be to upgrade to a modern system? And get rid of the original system?

I totally agree with Jack, I have converted a few R-12 cars over to R-134 & they are only 60-80% as efficient.  The way to do it correct is lots of labor, dirty & a PIA. The system needs to be flushed properly, all new seals , new compressor & dryer. Plus the fan motors in most C-3's are weak at best. Spend a little bit more & do it right...then be cool Cool

   I couldn't have said it any better Alan
But I have to add, One of the major diffrences between An r12 system and a 134a is the condenser. The 12 used a serpentine coil and the 134 uses a parrallel flow.
