here is hoping your rear is a 5 on 5.5----and either you go to a stock dodge truck 9.25 or pony up money to have someone build you a custom dana 60..... If you can find a Jeep Gladiator with a Dana 60-2 in back you are nearly there. The casting in the case web says 60-2. I have one of those units and had the drivers side axle tube and axle narrowed by 6". The axle shafts take Set7 Timken tapered roller bearings and are 35 spline, stock with a 5 on 5.5" bolt circle. I was going to put it under my '87 D100, but I bought a '98 Ram 2500 and sold the D100. Now I will probably put it under the '72 Cuda and narrow it again with different axles & brakes. The attached photo is of the Jeep that uses a Dana 60-2 rear with 12" brakes and 5 on 5.5" bolt circle. If you use 16" wheels they will clear the brake drums.

I put an 8 3/4 rear in my 86 RC 2wd with the last few years that had the 5 on 5 1/2 pattern axles(72 through 74 4wds?).
I'm now running a Dana 60 8 lug rear with 8 lug(heavy 3/4 ton front end) up front....all from an 85 2wd 1 ton. NOT that the 8 3/4 failed. I just like lots of woe...with the bigger breaks....lol.
I'm not a fan of the 9 1/4.....it seems that I've seen more of them being replaced than 8 1/4s......but what causes them to fail......who knows.
As in was it operator error......like taking them under water or letting them leak until there is no oil left, again my two cents.....which around here doesn't mean much. LOL

most issues I have seen or had have been the pinion nut coming loose/pinion bearing wipe out/crush sleeve adjustment or lack of.
every one I invested in got a new set of bearing and set up with shims and solid spacer. never issues after that with them.
I prefer the 8 3/4 for gear change and I can run non adjustable green bearings and Moser axle any size needed.
30 min R&R and either a 2.76 3.23 3.91 gear ratio under my bench.

I have revised my post about the Dana 60-2 and included a reference photo. See it a couple of posts above. I also have a 9.25" truck rear in my stash and when I have a chance I will drop it off at the recyclers. Years ago, at the yard I worked at, we took in a Dodge truck that had a 9.25". The pinion nut loosened and when the axle seized up the truck was wrecked
