Basically you want to find a '90-'95 ranger or bronco II with good front axle and MANUAL SHIFT transfer case.
Borg Warner 1354 Mechanical
Ranger, Bronco II 1990-1995
Electric shift would require quite a bit of rewiring and most people with electric shift WISH they had manual shift, lol.
If you have a manual trans now then you can swap tail shafts to add the 1354, if an Automatic the transmission needs to be taken apart to add the transfer case.
Look at the sticker on your drivers door edge, it will have an AXLE code.
Then look here to see what your rear axle gearing is: Ford 7.5 & 8.8 Inch Axle Tag & Door Codes
4.10, 3.73, 3.55, ect....
The new front axle will need to be the same gearing, in all probability you will have to change one axles gears, if your rear is not Limited Slip(posi-traction) then upgrading to that and matching front axle gears would be best plan.
You may need a different oil pan??
Can't remember if 2WD was different than 4WD
