well there are several diferences. is it a 4cylinder or a v-6 houseing? The gears are the same. The v-6 has bigger bearings on the carrier and some have anti lock break stuff in them. the housings are wider by three inches, and the rear brakes are bigger by like 2inches.
What else do you want to know. Oh yes you can use it. Swap the whole housing though. you will want wider anyways. Just take EVERYTHING from the parking brake relay back.
