Yes, you could convert to a later A/C compressor (post 86). They fit.

Look for compressors that have the letters "DK" in the model number on top. I like those because they aren't the Sanden ones that have to have the compressor seal changed if you convert to R134.

Then convert to 134. Add the condenser fan. Change O-rings, receiver dryer and expansion valve. Vacuum the system out and hold it to make sure it isn't leaking.

Then charge up the system. You should see very decent cooling with a 134 conversion. The problem with 134a conversions is that a lot--perhaps a majority--are either incomplete, or improperly charged.

Add the EXACT amount that the system requires, not in R12 figures, but in 134a. If you buy the Volvo kit, it says what the figures are. You can increase cooling by getting a light color dash cover (dashmat). The dashboard is like a heat machine in the summer sun.
