The system is a Frigidaire (GM) VIR (valve in receiver)
type system with R4 compressor like most GM cars of the
late seventies. I think if it were mine I would spend the
money and buy R12 to put in it as it sounds like it is
tight with little or no leakage. See if it will hold
vacuum. I have never tried to convert a VIR system to
R134a and have had conflicting advise as to how difficult
it might be. Sorry I'm not more help. Maybe someone else
will chime in.
