ok, may have answered my own question with a google search. If I am looking at quick connects it's already the 134a, right? Otherwise I would be looking at male threaded sorta "flare" style connections?
Based on these adapters it should be clear if the system has already been converted, right? does anyone have pictures to differentiate the R12 system from the R134a system? I'm not sure if mine has already been converted.
thanks,
