The stock system will be R12. It is very costly to recharge. If it is stock get a recharge kit. Kits usually contain everything needed to change to R134A refrigerent. If it is already changed then all you need is a recharge hose for R134A and of course some cans of r143a. You will be able to tell the difference in the two systems by looking at the A/C lines where the coolent is added. If they are R12 systems they will have threads if they are R134A systems they will have what are known as quick connects or simply there will not be any threds.
It takes R134a freon, that's it, no special type..........
