The 4wd Track/Kick tranny uses a married transfer case design, meaning it actually become part of the tranny and finishes the rear of the case. I'm not sure, but the 2wd tranny probably doesn't have any way to accept the Track/Kick transfer case without some fabrication. You could always use the 2wd tranny and get a transfer case from a sammy, they are separate or "divorced" in design and can be used behind just about any 2wd tranny... You might need new custom length driveshafts for that idea.
