I bought a Haynes A/C Manual and learned to do my own A/C work, to avoid constant trips to the A/C shop. My 72 Cheyenne has the same A6 compressor as when I bought it in 2003. I had the POA adjusted for 134a, new dryer and expansion valve and my A/C has worked fine in south Florida for over 10 years. My 1972 Cutlass, same set-up but also with a cross flow condenser pumps out 30 degree air from the vents. Also, same A6 compressor as when I bought it in 2006, and it hadn't been replaced in the 4 years the previous owner had the car.

I have a 1970 Bonneville that I am rebuilding. Classic Auto Air in Tampa suggested I get a rebuilt A6 right before I install it. The seals have a tendency to leak if they sit on the car or on the shelf and not used. Even a brand new seal can go bad and leak if the system is not charged and used.
