No he means Freeze12. To convert our cars to R134a it requires work in the expansion unit and additional parts. Freeze12 doesn’t cool as effectively as r134a but it is a straight change from any R12 system with no modification necessary.  
I will be charging my system with Freeze12 from Partsource shortly, but I need to get an AC Condenser.

Anyone have leads on an AC Condenser for a 1990 Nissan 300ZX Twinturbo?
