RE: axle??

2wd rears are 48" back-plate to back-plate. 4wd rears are 4" wider than 2wd for a 52" width b-p to b-p. The ZR2 rears are 3.9" wider than regular 4x4 rears, with a 55.9" b-p to b-p.

Here is a quote worth mentioning from hotrodders.com:

I have never figured why so many people go by the backing plate to backing plate. What I really want to know is where the wheels are going to sit. I always go by WMS-WMS (wheel mating surface).

2wd S10 rear end:
54-3/8" WMS-WMS
38-1/2" center pin to center pin.
Pinion offset 1" to drivers side (this was on my 8.5" axle and might be different on a 7.63" axle)

4wd S10 rear end:
From what I understand is 4" wider then 2wd so about 58-3/8" WMS-WMS
Spring spacing same as 2wd and I'm guessing the pinion offset is the same

Ford Explorer 8.8"
59-3/4" WMS-WMS
39-1/4" center pin to center pin (I have heard of people cramming these into S10's without moving the perches)
Pinion offset 2-3/16" to passenger side
There is a short side and long side axle shaft. You can narrow just one side and use 2 short side axle shafts. I don't recall how much this will narrow the axle but I think it will also put the pinion more in the center.
