If it's only the caps, I would NOT count on that - they could easily
have been placed back on randomly on a R-12 car, they are both 1/4
Flare ports.
This is why R134 ports are two different sizes - the low-hose will
not go on the high port, and vice versa.
The other big thing on a R12 retrofit is the compressor oil - R12
uses Mineral Oil. For R134 you need to flush 99% or so of the mineral
oil out and install a fresh charge of synthetic POE or PAG based oil.
Or the oil reacts with the refrigerant and turns to pudding, and you
know the rest...
