70 SX Tech Question
70 SX Convertible Air Condition System--Can you convert the air condition system from 12 to 134, or are further conversion parts necessary. Thanks--Joe Turchany
Good Morning Joe,

Keep in mind I'm not a mechanic, but I have converted my personal cars with input from mechanics. All they do is suck out all the R-12 and refill it with R-134A. No other parts needed for a functioning system. The only other input I did get is that if the oil in the compressor is old, change the oil and if the rubber parts in the A/C system are older (5+ years), replace them before you refill to avoid future problems.

I hope this helps.
