6 lug 2500 ld rotors, napa and oreilly has em I dont know about discount. You should be able to reuse your old wheel bearings. And for the rear end you could either get a 4x4 6 bolt rearend, or change the axles in the one you got now. If you do go for a new rear end I would personally get a posi-trac not the limited slip governated differential crap. 14 bolt is reccommended too.

So the 2500 light duty rotors are a straight bolt on? I heard that they work on the 1500 5lug. I wasnt sure if they fit an 8 lug. As far as a rear end. What is the fit for my truck? Would a newer disc brake setup require major rework on brake line system?

Ld rotors wont fit an 8 lug. The 8 lug spindle snouts are bigger. Why do u want to go to 6lug?

What? a "nicer" wheel selection? lol i think i've foudn better looking 8 lug wheels than 6. But to each their own. You probably gotta swap spindles.

Nicer wheel selection stock and aftermarket. And of coarse different.

Okay.......
you'll have to swap spindles and upper control arms. The upper bj are different sizes and mount different so you have to have 1500 uppers. Oh and you'll need need the brake calipers and shoes being that they're different also.
By the time you spend money on all this you could've bought nice wheels and tires.
