jeep grand cherokee 5.2 as donator for my dart gt -65, what gearbox should i use?

I just bought a 98 Jeep Grand Cherokee and it has a Dana 44A limited slip rear, not an 8 1/4. I do know that a lot of Chrysler 8 1/4 rears came in the 4.0 Cherokee. that's what I put in my 68 Barracuda. It has drum brakes, but the 98 Grand Cherokee discs will fit the 8 1/4. There's a lot of stuff that will have to be cut off of the rear diff and other stuff welded on to fit under the Dart.
I don't know how you would use the steering box. The steering orientation for the Jeep is in front of the axle.
Most of the 8.8's are too wide for the a-body. Been there, didn't do that!
