I have over 50 lbs of r12 ( my brother owns a appliance shop) I prefure r12 to 134a since its colder and the molecules are 10x larger so it leaks less. But it appears to have never been touched since 93. There are no stickers saying its been converted. And it's worked fine until now so its been reliable for 20 years

You need to find some adapters and check the high side pressure.

Would napa have them?

Maybe. The problem with R12 was that all the connectors were different between manufactures. Just like the diagnostic ports for obd1. Worth a shot though.

I didn't know that I hate that bullshit

Forget the 134A conversion just use 409A direct replacement no oil or seal changes
