Still got R12 and it is a lot colder than my 99 GMC with 134a.

R-12 fittings on the lines look like screw threads.
Retrofit units screw over those fittings, and they show no threads to the outside. The service equipment spring clips to the fittings.

Neither. I had R12, it went out, converted to R134 and now it's out too. And, I'm too lazy to fix it (plus I'm doing an engine swap right now anyway). It doesn't get that terribly hot in Texas...
