Some compressors don't like conversions. I would just buy a new one and use 134a. I wouldn't use anything not approved for use in automotive systems like freeze12 and others. Freeze12 is just 80% r123a anyways. Buy the right stuff and at least it can be recovered at a shop later if you have to fix the system. In california at least we have to identify refrigents now before working on the system, if you had freeze12 in it you would get turned away or charged a ton of money for disposal. The newer sanden type compressors are scroll type and are more efficent.
I want to run a homemade kit on my 56 3200 but can't figure out the bracket part. also the belt groove on my harmonic bal. is only setup for one belt, would I need a longer belt or another harmonic bal. for two belts? also where would the compressor go, etc... I figured I'd buy the under dash kit from vintage air or get a vintage air off ebay. I heard you can't get brackets from them....
