Was the condensor and evaporator coils from the '92 or a 67-72? Just wondering as I read others say that the 67-72 condensor is too small to efficiently cool on 134 systems. The '92 would have been R12 so just as transformula said if you go with R134 it would need flushed and have PAG oil added. The compressor label should specify how much oil the system needs. I dont recall the weight maybe PAG100? there are several PAG oil weights hopefully someone else can verifty the proper oil weight for you.
R12 cools better but costs a lot more while R134 is readily available and costs less. I converted my '93 from R12 to R134 and it works great. I also changed all the o-rings and seals out with the new green ones that are supposed to be for R134 but have seen plenty of people use the old black o-rings without problem.
