I have a 01 also and just replaced the rotors. I have found nobody to confirm that Ford makes two different rotors (Motorcraft and OEM Ford) for this vehicle (including the parts guy at MLD). From a manufacturing perspective, it makes no sense to make two, but, from a marketing perspective, it does make sense to sell two at different price points. I priced both at two dealers and the Ford model were less expensive than the Motorcraft (surprised the parts guy). I have not seen the Motorcraft, but I'd bet (a small amount) that they have the forged Bosch name on them as do the Ford part.
I went with the Ford part because it was less expensive (at the time).
