This is for may "87. The high side fitting on the compressor looks like a combination schrader /quick connect ,but is not the standard 1/4 sae fitting that fits the manifold gauge set. Anyone know if there is an adapter an adapter available.

 

Anyone ever find out which high side adapter should be used to attached the AC gauge set?

 

FYI did it get a retrofitted to R134? Since those cars are the R12 system and they have a different fitting and they they have not been converted to R134 then you need to take to shop to evacuates the R12 and get a fitting adapter for your car otherwise it not going to connect it

 

No, it does not have the R134a conversion. I want to connect a R12 gauge set to check the pressures . The R12 adapters are still available for other makes, so I wanted to see if anyone had a source for the Max.
