From what i've can tell, the difference seems to be where the shifter housing (??) bolts on. Again I'm pulling this info from MC, going off the pics on the transmission thread. Theoretically if I can get my hands on the section of the tranny that the tcase bolts too, that section should bolt to my tranny, right?? Now if thats the case, will any top shift tcase bolt up or will I be sending MC some of my $$ to correct this issue?
