My VR4's AC is in need of a recharge. The previous owner took good care of it and I'm not sure if he converted the AC to R134a. Is there a way to tell if he did?

You can look to see if it has R134A adapter fittings or a retrofit sticker. Even if it doesn't have those things, it could still be retrofitted. Take it to a shop that has a refrigerant tester to see what's really in the system.

Regardless of what you have in there, unless you want to pay $150+ (average cost in my area for the amount a galant takes) for the R12 alone, not including evac and recharge, you'll probably want to have it converted anyways if it needs filled. Just make sure you have a reputable shop so it. The condenser, compressor and seals are both PAG oil compatible and R134a compatible (lots of domestics of the same era are not). 134a takes roughly 3/4 the charge of R12 to cool properly, so if a shop looks up R12 and fills it with 134a to that spec it's going to cause issues being overfull just an FYI. (I'm an AC tech in Arizona)
