Using mustang rotors for 4.5" bc

Just looking for the height of the original Mopar rotor hub or the finished product like in the picture you posted. I’m having the work done remotely through my dad and the measurements are all the machinist really needs. Micrometer measurement of what’s pictured.

Oh right, Im not sure what that measurement is. I gave my machinist the new rotors and the original ones to match them to. I could measure mine but I dont want to give you an inaccurate figure. It might say farther back in the thread.
