Disc brake/spindle ID

Can anyone help me positively identify these?

Thank you.

kelsey hayes 4 piston stock front brakes.

65~72 for a body although they also came on B & C bodies as well.

These are 4.5” bolt circle on A body spindles. They allegedly came off a factory SS Dart but memories can fade, and many cars come and go over the course of 55+ years (has it really been that long?!).

Are there any ways to verify?

interesting. i was under the impression that you couldn't run the BBP discs and calipers on the A spindle because it was too short and the caliper did not bolt up.

is it possible the hub has been redrilled?

anything is possible when talking about these cars, but the documentation is out there for them.

KH disks with a modified Mustang rotor? Would give you a KH disk brake set up with a 4.5” bolt pattern…
