Thank you.

I should know this but I dont....I think I have a 203 T-case and would like to reuse it if possible.

This is a long bed truck...if that helps with discussion.

I see that there is a tail housing extension and an output shaft that are specific to 4x4. Are those the only 2 major components that I need?

BTW, I received the 8.1 and trans yesterday. Pretty cool stuff. I am anxious to get my shouse (shop-house) completed, get the 2 post car lift installed, and really get on this swap.

Thank you for the replies/information.

Dan
