Using mustang rotors for 4.5" bc

So from what i see here the 6004R rotor for the 66 mustang and the 40154S National seal are the parts I need to do this conversion?. Machine the inner bearing seat down by .271 and cut the rotor down to 11.09 and remove the inner hub surface down to the seal surface to clear the dust shields. Just want to be sure Im not missing something. Thanks in advance. Looking forward to doing this!
