I was just curious I havent figured out the engine replacement or anything I just wanted to get a genaral Idea
about how to link the 2 diffirentials [color:"black"] [/color]

take a tandem axle setup out of another pickup and throw it under the ranger may have to shorten things and have some stuff fab'ed though

Could you tell some of the other models that have a tadem axle I know of the dodge t-rex but every thing else is way to big for the frame that I know of There was a setup using a transfer case and a chain but I dont think that would hold up very. anymore suggestions would be greatly appreciated.

If you have enough room for it use an old ford single speed transfercase turned around backwards behind your other case. You will have to mate the cases somehow and install a yolk where the old input used to be but that would give you 2 outputs then 1 for each rearend. use rear axles with offset diffs and a driveshaft with a carrier bearing for the rear most axle to go over the center axle. Sounds like a lot of work huh. You could use rockwell axles out of a larger truck they have flanges for just want you want to do. that is if you are going big. GOOD LUCK
