Starting a new project car and need help with parts interchangeability

For a nice rear end conversion that will gain you rear discs, an 8.8 Ford rear out of a 1996 or newer Explorer will fit very well if you are willing to use Mustang deep offset wheels. They can be found all over with 3.55 gears, psoi, 31 spline axles, and discs stock. Just be sure to grab all the parts you can at the bone yard like the companion flange for the driveshaft, the bolts for it, and the brake lines, as you can use two factory Ford rubber lines to hook to the Mopar system.Two things need to be done.The front wheels can hit the upper control arms due to the deep offset and I had to go with triangle shaped tubular upper control arms to make them work. The rims I used were 2006 polished 18 inch aluminum five spoke with 6.3 inch back space by 8.5 wide. In back, I had to move the springs into the frame rails to get clearance, but now have some 245 x 18s back there. Makes for a great stance and appearance. On the steering box, is there an after market company that makes a small power steering box? It might be your solution, and the power will be a great help with those wide weenies up front.
