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.
