I converted my 92, but it was not easy.
R12 switches and hoses are SAE threads (American).
All switches and hose fittings for R134a are Metric.

I bought entire new 95 R134a system; evaporator, condenser, dryer, hoses, switches.
Took months to gather all the correct stuff.
Took about a week of wrenching to get it done.

The most difficult part to get was the hose set the attaches to the compressor. No one makes it and the hoses out there are all built incorrectly.

Here are my build/problem threads
