Using mustang rotors for 4.5" bc

Just to clarify, apart from turning down the outer diameter, in the first picture the highlighted outmost surface has to be cut down to the same height as the original disc and in picture two the bearing has to be removed and its seat has to be lowered by .271?
Last pic is an original disc for refernce.

While visiting my family in Oklahoma for a funeral, my dad and I met with his machinist friend. The guy is amazing. Can custom make ring gears, pinions, planetaries you name it. He’s done this type of rotor work in the past. Pallet loads of rotors that he machined down for some company back east. He’s semi retired now but got the good ol boy shop rate.

Machining to be done

1. 11.00-11.09” rotor diameter
2. Inner Race seat machined down .271-.275”?
3. Hub height to match Mopar original. Does anyone have the mic’d measurement for the original inner rotor hub height? Need to know how much needs to be cut down to match the Mopar originals. Thanks in advance.

If all goes well I might get a few sets done and offer them here on FABO. It’s a niche market but seems like a great way to get BBP with minimal alterations.

Wonder what people would be willing to pay for already machined rotors? $300 for a pair?
