Has anyone ever done this? Here's what I have: I would like to upgrade the G80 axle on the 'nali with a 14b SF off a 99 Silverado 2500 which happens to be the same 3.73 ratio, but it has 8 lug pattern axles. Would it be worth swapping the front 6 lug stuff to the 8 lug? Is it a bolt on endeavor? How about the control arms, I noticed the HD ones off the truck are forged as opposed to the welded/stamped steel ones on the 'nali, can these be swapped in as well without major mods? Any and all input welcome...
