Mike, I know the '97 takes 2 lbs R134 and I posted the PAG oil capacity a while back too (can't find it right now). However, you really need to get input from someone with the '95 FSMs before you do too much.
Has or will the system be completely evacuated and all the components replaced? If not, then the amount of PAG oil you put in is determined by which components you have replaced and how much oil you got out of them. Too much oil isn't very good for your system just as too little is bad, just for different reasons.
