need a rear end

[lrader99]

so this C30 i have been looking at is not so good in the cab section. and i dont need another junk cab parts truck...What i do need is the rear end.

I want the narrow dually rear end.

I will end up boxing my C10 frame and slapping that bad boy under my 127" frame and rolling with it. Any one know of a stash pile of such rear ends? What is there specific name? are they Dana 60s or 70's, 12 bolts or 14 bolts....all i know is that its an 8 lug narrowed dually and i want it!

oh and how do i convert my 5 lug C10 front discs to 8 lug discs
