Take the rotors with you when you drop off the parts for machining. Clean down to clean steel at the critical areas.

Yep, the plan is for a good rotor/hub fit such that "0" radial movement would be allowed. I suspect the Chev studs are smaller in diameter than the Toyota and thus the studs must only serve to retain the rotational position of the rotor, not in the radial position.

I did think of replacing the Chev studs with metric (to match the rears), but I want things to be easily reversible (a bit silly I know but there it is).

the machinist is going to want to know the hole diameter of the rotor to ensure he machines the old truck hub to fit properly. I checked the napa site and this is the info I came up with for the hilux. hope that helps. looks ;ike the inside diameter of the center hole is 108mm.
