    I have a 86 And need to get a/c running. I want to replace to newer freon what all needs to be done to get a/c converted to R134A??

    my compressor seems to went bad and will need to replace as well.

    I did my 85 about 8 years ago, had it done with the old freon and it cost me $2300.00, Just a heads up, You will likely need more than a compressor.

    No conversion, just had it restored to working condition, I wanted to convert but the mechanic said it won't blow as cold.

    You will need to change the oil in the compressor, the seals, and replace the receiver/drier. You will need retrofit valves for the ports. IIRC you can only charge to 80% with R134a before the seals will blow, so it will not blow as cold when stopped and idling.

    Did my 1985 last year. Total $940 out of pocket, however my compressor was good and I had accumulator already. Putting evap in dash sucked. If I had to do it again I would definitely pay someone.

    Oh yeah, and replace ALL the o rings whether they look ok or not. My coolant leaked out 2 times on me because I didn't put in new $.80 o rings
