Hi,
whats the simplest way to to change from 6 bolt to 8 bolt wheels on a 10 bolt chevy front axle?

Are there moore ways to do it ?

you will need 8 lug hubs, rotors, studs, and backing plates (and wheels)
the spindles, calipers, lockouts, axleshafts on the 10 bolt are same 6/8 lug so you're good to go there

u sure u dont need new backing plates? i know on the dana 44 it requires new backing plates..

Is there factory built 10 bolt axles with 8 bolts? if not, from whitch axle do ya take the parts needed.

Is it possible to fit bigger brake rotors from a bigger chevy?

Mechted covered it!!! Make sure you use the correct calipers for your backing plates (with or w/o bumps) or you'll be grinding on the back plates.:flipoff2:

You can also use Dana 44 Chevy 8 lug stuff from 77 up , same spindles etc .

You just need to use the whole setup if you use a pre 77 d44 . The pre 77 spindles is smaller OD and take a different bearing . But the spindles bolt on to a 10 bolt knuckle .
