I have something pretty close to your desired rig. As the saying goes, there's the good, the bad, and the ugly.
Specifications:
It's a 1987 Bronco II 4x4. The factory motor has been replaced with a 1992 4.0 from an Explorer sport.
Transmission is a M5OD that I got from the same Explorer sport that the motor came from. There is a tag on the tranny from a local business that suggests it has been either serviced, rebuilt, or replaced at some point. I don't remember the date on the tag, but if you are interested in this vehicle, I will crawl through the snow and verify the date (I want to say it was done in 2000).
Rear axle is a disk-brake 8.8 from a 2000 Explorer, and I have added a Detroit Trutrac differential. 4.10 gears. Riddler diff cover.
Transfer case is a manual shift 1354 from a Ranger (I don't remember the year).
Front axle is a Dana 35 from a 1992 Explorer (but the front axle came from a different Explorer than the engine and transmission came from). 4.10 gears. Brian1's front diff guard. All four ball joints were replaced within the last two thousand miles.
4" Skyjacker lift and 32" tires.
The good:
The engine runs great; it starts quicker and easier than any vehicle I've ever owned, no matter how long it has sat. The 4L motor and 4.10 gears are a good match for the 32" rubbers. This thing does very well offroad. The body is relatively clean: there is some rust and some rot on the exterior of the body, but the underside looks great. When I did the motor swap, I replaced the clutch, water pump, all coolant hoses, tensioner, as well as MANY gaskets on the engine, such as valve covers, oil pan, exhaust manifold, and more I can't remember right now. It has the radiator from the 1992 Explorer sport. The front bumper has been replaced with a minimal winch-mount bumper. I will not include the winch with this sale. I am likely missing a lot, because I have done so much to this vehicle, but if you have any questions, I should be able to remember specifics.
The bad:
The wiring under the hood is messy. I have thought about cleaning it up, but it is all functional, so it hasn't bugged me enough to change it.
The transfer case leaks out the rear output seal. I have tried replacing it twice, but I can't get it to seal.
Motor leaks oil from somewhere. I think it's from the oil filter adapter, but cannot confirm.
The ugly:
Rear hatch release handle needs to be replaced; it has a broken snap-ring that prohibits it from working.
Driver's side window guide is broken, so window doesn't go up without help.
I'm sure I'm forgetting a lot. I have owned this vehicle since 2009, longer than I've ever owned any other vehicle. It has been used offroad, but it has always been extensively maintained.
I won't let it go for less than $4500.
Let me know if you have any questions.
