So Scarebird it is!

Correct! Had to do the same thing with my set up. Not sure about your calipers but mine were bought at the same time from the same company and they look completely different. One required more grinding than the other.

LEARN from my head ache and counter sink the back of the rotor holes you make. Took me forever to figure out that my rotors were the reason my rotors weren't sitting flat had to do with the studs hitting the inside of the rotor hat. The hub of the rotor is what will center it so if your holes are bigger its not that big of a deal.


I also had one caliper not fit correctly and ground off the bump, the other side fit perfect, I now have 2 matching (bendix) calipers for the other conversion in the wife's 66 dart.



Also to for making the changeover easier I replaced my studs with the screw in type so that I didn't have to countersink the rotor in case I ever changed to a different type of rotor or ruined the ones that I originally bought to use with the scarebird setup.


Now I have the option of using either the 5 on 4" and drilling a rotor or the 5 on 4.5 by just unscrewing the studs from one set of tapped holes to the other set. I had the 5 on 4" SBP torque thrust mags on at first then went to BBP rally's because I just like the style better(after I find matching center caps that is).
