NP241 wide bearing case id?

[albersondh]

Im looking at a few 89-91 241C's at the moment from Suburban, Blazer, but Im not sure how to ID a case with the wider input shaft bearing? I have a special input gear I have to swap in to make my trans work and it is a wide bearing gear. Im guessing that the housing between narrow and wide input bearing is different. If not, that's good news, I can grab any 241C and swap away.

I thought they were the same until 95, with the 94 back being around .937 wide and the 95 up being .6xx. All other dimensions being the same.. I know they changed input/planetaries around then if remember right.
