8 3/4 Rearend Question

I can't see why you can't make it work. I do think you'd be better off farming it out to someone with a jig so the ends get put on exactly straight. Anybody can put them on but even the best of us can probably only get them within .100 which would probably eat the bearings out. Maybe even do more damage. The width from axle to axle is 55.6" and the spring perches are 43.0" apart. The perches shouldn't be any problem for you to do though. You'd also need axles unless you already have them. The Yukon axles are a nice upgrade and the price isn't too bad. By the time you find stock axles and have them cut down and resplined and hardened you'd probably have 3/4 as much as the new Yukon's cost.

Here's a page that has a ton of info on the 8-3/4. It will probably answer any other question you have.
