Re: 8lug wheels

As far as wheel clearance, I believe the frames are the same. Dually trucks usually utilize a wide hub spacer in front of the drum/rotor to space the deep-dish wheel away from the suspension and brakes. Not sure if this will mean a spindle swap or just rotor/drum swap to convert, though.

Re: 8lug wheels

Are you wanting to convert to disc brakes? Either way I think you have to swap spindles 71-up for disc but your a-arms should work but you will have to change upper & lower ball joints to fit the spindle if you were closer I'd give you a pair of drums and spindles off a 68 C/30 if you want to pay shipping I'll send them to you thanks Jeff
