The 95 ZR-1s have 134 AC. I do not notice any difference as I have both 90s and a 95. You can get as much R12 on Ebay as you want for about $30 a can.
There are lots of stories and recommendations for the R12 to R134 Conversion.....both some negative and positive. I think the AC Compressor operates at a higher pressure with R134 for example but you would use the existing R12 compressor with R134.
I just seen you are changing compressors anyway.
There exists several R12 to R134 Conversion Kits which include the Compressor, Oil, Expansion Valve and Dryer/fittings. First thing you have to do is vacuum out the existing R12 System.
I was thinking of doing this conversion with a 1993 Ford XLT but have found the Original R12 Compressor was leaking oil so will stay with R12 system and just have the original compressor replaced.....let us know how it goes
