Hi all - has anyone with a 1961 or earlier air conditioned Mopar had any experience running R134 in the early '57 to '61 compressors? I've been told they can only run on R12. R12 is illegal and unavailable in Canada. (Consistent with the left wing leanings of our governments, the fines for possessing R12 are higher than the fines for possessing crack cocaine........) I run R134 without any problem in my '66 Charger, so the new '66 300 should be OK too. The concern is with the earlier A/C unit in my 300F.
