The short answer is none! I believe rotors are used from camaros or 1970s 4wd trucks. The camaro uses a hat to space it out. The 4wd rotor uses the stock hub.

There are kits available complete with every part you would need for short money. Yes, you might be able to come up with something that may or not work on your own. These kits remove all thought, and most chances for error. IMHO they are well worth the money.
