Need Help With Trans Case
 

So, just picked up a 91 v2500 Suburban np241c.The trans case started leaking. Long story short, the rear bearing housing was cracked. I got a replacement housing off of a pickup, but it is a little different. The tag said it was the 241c,so I figured it might be the same. Does anyone know where I can get the interchange info so I can get the correct one. Thank you!
