Air Conditioning Question
I have a Low Pressure guage for what I KNOW to be for R134a.
My question is, are the fittings for 134 and 12 different so that my guage
will not fit any of the pressure ports on a R12 system?
I have a car in the driveway, and my guage fits the Low Pressure side. Since
my guage is for a known R134 system, then the car I'm working on is also
134, right?

Yes, they were designed exactly that way to avoid confusion and mistakes. Since R-12 is not compatible with 134a.
They make adapters for the old hoses, that should give you an idea.

That would be a good assumption but you should look on the radiator shroud, on the accumulator, or on the compressor for the
refrigerant sticky, just to be certain.

Also a 134a gauge is different from an r-12 gauge in pressure readings are
calibrated different and you should never use 134 gauges for 12 and visa
versa due to oil contamination and incompatibility. I have 4 sets r12,
134a, puron 401 and freeze12.
A quick check to see if you are low with out a guage is to measure the
temperature of the liquid line it should be between 50 to 57 degrees.

little topic drift, but the low side R-12 gauge with long hose makes
a dandy fuel pressure gauge for diagnosis. Just ductape the sucker
to the window, screw it onto the rail, and drive.
