RE: Air conditioning R134A swap
I found on the web some documentation from Toyota about the R12 to R134 conversion. And basically they change the orings, the compressor oil, and that's it.

The expansion valve is not mentioned.

Mine blew away after I filled the system with gas... bought another one brand new, but haven't tested it yet.
