I noticed my A/C gauge set for R12/R134 hose fitting for the high side is too big. None of the adapters it came with fit either. Did my round the town quest for an adapter, but no one seems to have any R12 stuff. Anyone have a brand & P/N I can order one? I did buy an adapter that someone suggested at Discount Auto, but its a no go too.

Oh, its a 90 Convertible

 

What you are looking for is a 1/4"x3/16" service port adapter. A good NAPA store should have one now that you know the exact terminology. If you cannot find it locally, here is one on ACKITS.COM.

Thanks Jackhild59! I browsed the web forever before but I didnt really know what I was looking for. I printed it out and I'll bring it to an A/C shop tomorrow. Gonna bring my a/c line as well to see if they can swap the hose. The hose fitting at the condenser wont budge.
