Look for a front rotor from a 3/4-ton Suburban 4x4, circa 1985. They are separate from the hub. Like this: They are, however, designed to be mounted on the backside of the hub, so you may need to use the lug bolts from that vehicle too, and have the holes in the hub opened up a bit. They register on a shoulder on the hub, so a little machine work to produce the shoulder on the existing hub would be in-order. You might be able to get them on from the outside of the hub with some machine work too. The calipers that go with these are cheap, and are of the two slider-bolt variety, which are pretty easy to mount: If you go the mount-from-outside-the-hub route, pay close attention to the inside of the rotor hat when selecting them. Some aftermarket rotors are machined in this area, some are rough finished, even inside the same store. You will want the machined ones. In this case, you'd turn down the hub so the rotor registers on the o.d. of the hub with a gentle press fit.
