Al,

	The R-134a compressors are typically higher capacity because 
R-134a is not as efficient as R-12.   That's why the shop suggested the 
possibility of using an additional fan on the condensor.

Did they replace all the seals with R-134a-compatible seals?   R-134a 
has smaller molecules, so it leaks out of R-12 systems pretty easily.   
You'll likely have to recharge it more often.

I'v ebeen thinking about using a compressor normally designed for R-134a 
on my wife's T-Bird, and charging the system with R-12 for a really coold 
A/C system.
