Thanks everyone that had pertinent input, others, not so much. I'll do some checking in the local yards, I guess the 3500 is Alum. case, built in bell, the 4500 is Iron? and separate bell? Just wanting a manual w/od, easy shifting. The Rockland Std gear is a bit spendy, and needs to be drilled/tapped for transfer case the way I understand. Thanks again.
