Two ways to go about it.
1, find a rotor that fits around the hub. This is what CPP does, I think, and what most modern brake systems do.
2, put the studs through the rotor and then into the hub, press to fit. This makes a single piece hub-rotor, if I recall correctly a rear wheel drive Astro is set up about the same.
If you go with option one, which will be easier, you just bolt the wheel up to the hub & the rotor gets sandwiched. It won't go anywhere - but you DO want it to be centered on the hub, so a machined spacer ring may be needed.
EDIT: Also, lots of companies make hub-centric rings to adapt lug centric wheels. You may be able to find some in the right size to center the rotor.
