Which refrigerant in 1993 90Q?

[James at ringsperformance.com]

> You can tell by the fittings,

Specifically, if it's R12, both fittings will look the same, with external threads of the same size. If it's R134A, the fittings will look similar, like little quick-disconnect airline fittings, but different sizes.

Nothing should happen if you remove the cap(s) for inspection.
