A/C Fix it yourself? Freon/134?

Hey guys,
I just bought a 92 LX that hasn't moved in 15 months. I live in Orlando, and have to have some A/C and this thing just blows out hot air. I just sold my 95 Cobra that had R134, do the 92's have 134 or Freon. Assuming that there are no leaks and the system is good, it there a do it yourself kit to re-charge the A/C? Do I have to convert to R134? Is there a driveway conversion kit for that? I don't want to take is somewhere and have some moron tell me it's gonna be $600 bucks because of this and that.

Thanks-
