Using mustang rotors for 4.5" bc

Next problem was possibly because I didn't have have the race area cut deeper, or maybe its just manufactureing tolerances on these old mopars.

The disk was not even close to being centered in the caliper as you can see from the pic.
For some reason this was only a problem on the drivers side. Passenger side was much closer to being centered. (not perfect, but close enough).

Solution was to shave about .050" off the mounting bosses on the caliper, so that when it was bolted back on, the caliper would sit farther out, and be more centered on the disk.

I have a before pic, but didnt take an after pic, but after this mod the disk was much closer to centered in the caliper.
