    I would say most likely 3.73's, but my '89 Burb came with 3.42's, so either one, another friend of mine with ab '87 had 3.73's in his.

    I've seen that "build sheet" on the glove compartment door,and also under the hood on the drivers side inner fender in the middle of the hump for the tire in many of the trucks I've checked out in the boneyards.I also found the original work order(the paper that tells them what to install for options,etc)tucked into the seat springs--makes for some interesting reading.The one for my van I found stuffed into a hole in the frame where they'd tie them down on a car carrier--18 years later!. I got pretty excited --at first I thought it was money! /forums/images/graemlins/eek.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/frown.gif /forums/images/graemlins/angryfire.gif
