the engine can be made to fit without too big of a fuss, but that d20 wont live for 10 seconds behind an engine like that.
If your FSJ has the front axle gearbox (the diff)on the passenger side, then use the entire drivetrain from a 89-93 dodge 4x4 Ram 2500 or 3500. hell, just put the jeep body on the dodge frame.
those years of dodge ram (generation 1) had dana 60 front axle, dana 70HD or dana 80 rear axles, and the 5-speed manual came with an np-205 mated up to it, all behind the 12-valve cummins I-6 diesel. A word to the wise... do not use the dodge automatic transmission or the Getrag 5-speed manual. Make sure to get an NV-4500 manual 5-speed trans... the autos are problematic and the getrag 5-speeds are absolute junk. Make sure that your Cummins is not a "53" block (casting #53)... they are crack-prone.
I would suggest you get on the turbodieselregister.com forums or the dieselram.com forums.

GM front D60 would be an easier swap, and then a dodge rear axle from a early to mid 80's ram would be bolt in as I recal. Then you have no perch moving.
