I'm telling you, a lot of us have done a lot of research on this upgrade. It all boils down to this.

Measure the u-joint on the SR and compare that to your truck. They use the same joint.

If they are the same, bolt the rear into place, if they are different, wait for the right one or modify the drive shaft.

It's that simple.

PS. we went though that flange thing, pinion thing, drive shaft thing............ I bet if you did a search you would find more information than you'd ever need. There is even information on the new 4x4 wire portal, but for the Gen II.
