I bet you could find some rotors like that on wrecked cars in the junkyard.

I remember going with my dad to get a part for his pinto (I forgot about that one til just now). We saw at least three of them in the yard with rotors similar to that....actually they were worn to the ventilation cavitys on one side because the floating caliper stopped floating!
