purpose of the truck is for mild wheeling no rocks mostly mud and sand. running 33 swampers at the most maybe go 35s. i can get a free matching set of frt. and rear 12 bolt 6 lug axles full width from 80s style chevy 4wd. not worried about rims because theyll be free also. do you think its would be worth it to go full width. i priced 4 wheel parts amc20 inner shafts was about $280 and a locker also $280, front inner shafts was about $500.is the 12 bolt even an up grade or just as doodoo.
