I used my original hubs. Be sure to have the backside of the hubs turned so the rotors set flat against them. I also changed the wheel studs to longer ones.
Don't forget to buy the roller bearings for your axle. They fit right into my hubs.
It was a 2 step process at the machine shop to remove the studs, turn the hubs elsewhere, then back to the machine shop to install the new studs and races. ( the machine shop wouldn't turn the hubs)
