does someone re pop the kelsey hayes rotors with a 4" bolt pattern? The 68 stock set up? I read that 65-67 mustangs used the same rotor? Is it interchangeable with the dart?

Same calipers, but different rotors and hubs.

You may be able to buy something from a local parts store depending on how good they are and who their distributors are. Bendix used to make replacemnt rotors (but the casting on the hat slightly hit the calipers), and more recenctly Raysbestos and Borg Warner. Often the biggest problem for the parts guys is finding them by 'application' in the books or 'puter.

i may be wrong but sometime ago Goodmark industries casted a one piece rotor that would work with the 1966-69 bendix 4 piston brakes. I believe Frank Mitchell was selling them . i found a set of NOS mopar for my charger 12 years ago. there probably are original bendix rotors out there.

My buddy bought a set off ebay for $55 to the door. That was for 2.
