Well that fitting worked and ice cold air. Its April now and took vette for ride. All the Freon leaked out over winter. Well back to the drawing board.

Below is a link to Red Tek's web site. Have you tried the stop leak they sell? I know it works well in 134A systems as the stuff leaks past the seals because the molecules in 134A are smaller than R12, thus the reason why our new cars usually need a charge after 3 or 4 years. Wherever there is a leak, this stuff seals it off and never leaks again. No large holes, just tiny ones like seals or pin holes in the evaporator core.

I haven't tried any stop leaks on my system. I believe those products are mostly a seal conditioner. They operate on the assumption that the seal on the compressor has gotten hard and inflexible and lets freon by due to it's inability to "grip" or seal on the shaft that goes to the clutch assembly.
My system still has the old hoses and it's likely that is the source of my leak. I have a leak detector and whatever leak it has is so small that the detector cannot detect it, running or not.
I have a 30 lb can of 134A so it's not a big deal to top it off each year.
Even my daily drivers need topping every second or third year it's the nature of automotive A/C systems. I have had some that last for years with no service and some that need it every year.
If you don't have a leak detector then a dish soap water mix in a spray bottle is pretty effective at finding leaks at connectors and even the out put shaft behind the clutch assembly.
If it leaks all the way down to atmospheric pressure then it's more of a serious leak, and will require repair and vacuuming down for re-servicing.
