Fzj80 transfer case into uzj100

[cybrstar]

I have noticed that my transfer case on my Uzj is weeping a little from the front seal and I know that Both the Uzj and the fzj both uses the same transmission.

My question is "are the transfer cases the also the same"? Only reason is that I have an fzj80 late model transfer case that is laying around the storage that I would like to swap if I could.
If they are not the same, I know that they must mate since they both run the same transmission....
Do you think I may have driveline issues and new drive lines may have to be made?

The 100 series does not use the viscous coupler. FWIW.

If that's the case, rear driveshaft will be long ~5".

Out of curiosity, is replacing the front output seal that much more difficult on a 100 that swapping transfer cases is the lesser chore?

I have one installed with Marks gears and custom driveshafts. The drain port sits 1 " further forward and that the speed servo is the same. Can give measurements if you need them.

Edit: Re-read your question. You will definitely need custom driveshafts. Mine are OEM'ish.
