    I've done some searching and want to be sure I've got things right. Is the following information correct for a stock 1991 full-size Jimmy?

    1) GM 10-bolt front and rear
    2) Limited slip in rear
    3) Gears identifiable with these codes:
    GU2 = 2.73
    GU4 = 3.08
    GU6 = 3.42
    GT4 = 3.73
    GT5 or GT8 = 4.10
    G80 = Gov-lock
    4) 4L60E transmission (for automatics)
    5) TBI 350 V8 with 210hp/300ftlbs
    6) Automatic locking hubs in front
    7) NP241 transfer case
    8) 1/2 ton suspension
    9) Front disc brakes

    Also, what size are the stock aluminum wheels with holes in them? 15x8?

    Thanks for any help!

    Thanks, txbluethunder. That page is where I began my search. It helped answer a few points.

    <font color="green"> It looks like those specs are right with the exception of the tranny. It should have a 4L60, not the 4L60E. The only difference is that the E is electronically controlled, they didn't come out until a bit later. </font color>

    I think your wheels are going to be 15x7. Check your driver's side door above the latch w/ door open. It should tell you there.
