1972 Scamp in New Zealand

If the rotors are the smaller 10.8" dia BBP 14s should clear. My 74 dart parts car had that diameter rotor, and 14" rims. Show us a pic or 2 of the calipers and mount brackets. I bet they are the same or similar to U.S. spec ones.

If you go BBP fronts, will you upgrade the rear to BBP as well? I am upgrading the front and rear on my sons 69 barracuda to BBP. Using M body front discs, and a ford explorer 31 spline 8.8 disc brake rear axle. Even had 1/2" RH lug studs. Not sure but aussie falcon rear axle may work for you. Maybe the hotter V8 GT falcon with the good gears and a locking diff? It may be an 8.8 as well. Parts are plentiful and dirt cheap. I know the ford pass car and light truck axles in the U.S. are same bolt pattern as mopar BBP. Not sure about OZ or NZ though.
