all 92s had 4 Bolt rear ends.
easy way to tell about the motor....
Big Brakes - 7 bolt motor.
small brakes - 6 bolt motor.
I haven't found a oringinal car to prove me wrong yet on this one.

Flubyux2 - why would you want a rally car in florida? where would you even take this thing out?

7 bolt 1G motors are fine. I would have no problem building one myself. Main supports are stronger as well. How many 1G 7 bolts do you hear about walking? about the same ammount as 6 bolt motors.
