Can't find one? I may have a solution...  It's a pricy one but I'm not apologizing for that. As more folks utilize this path, the prices should come down. I wanted an exact replacement- I just did. I did find one NOS rotor for $200 but could not find another. So after calling many folks and shops, I was put in touch with Coleman Racing products who said they could reproduce them exactly. I sent them my only NOS rotor and they created a separate hub and rotor assembly where if I need a rotor in the future, I just replace the rotor part, not the hub and rotor. I will put all the details on how to get these if your interested. NOS rotor on right side.

Installing them I found that the dust shield bolts and lower caliper mount bolt interfered with the rotor to hub assembly bolts. (See Pic-Caliper bolt on top with 1 of the dust shield bolts below- note: dust shield removed) I had to replace the dust shield bolts with socket button head 3/8" 16 x1/2" bolts I ordered from Bolt Depot for $38. (See Pic) I had to grind them down slightly to clear (See Pic-NOS dust shield bolt on left). Since I could not use the star washers, I put Loctite on the bolts. Also had to grind down the lower caliper bolt- (See Pics).

Again, I'm not apologizing for the cost although once you replace your rotors with these, you only need to replace the rotor part if needed in the future. All bearings and races /parts remain NOS- off the shelf.
