Not a single response...
So i went ahead with what I perceived to be logical.
I just got the engine and transmission back into the car yesterday so its been a slow process and still a lot of work to do.
I bought a new compressor and dryer. I took both the rad and condensor to my local rad shop and had them tested and cleaned.
The hoses all 'appear' to be okay, no cuts, chaffing or splits.
I plan on connecting the hoses to the condenser, but will let the AC specialist remove the caps off the compressor and dryer to make the final connections and let them vacuum the system and pressurize it and pray there are no other leaks.
I'm going with the R-12 and hope for the best.
