Try NAPA or a mom and pop parts place. I found mine thru a independent parts store. The American made were around $60 each but on backorder with no ship date. I ended up getting the other rotors available (chinese I assume) for $29 each.

Went and found the box, Made in China. Mfr was ABS Brakes Inc, PN BD60257. I couldn't locate this number on the web.

Autozone has some listed, PN 5384, $84 each.
