Using mustang rotors for 4.5" bc

Machine work cost me $300 bucks. My engine guy wanted nothing to do with it either. I had to look around to find someone willing to try.
someone with a good 4 jaw lathe should make a couple dozen of these.
Like the machine guy said, the first one took 3 hrs, the second one 45 mins.
Good luck with the brakes. It was well worth the cost for me.
