dgt1972-----Great Insight, Attitude.
Yes, Go Stock, Correct Braking, not Elaborate, Pieced together Brakes.
AND, Yes, the 67 - 6 Cylinder Spindles will infact accept the 5 Bolt Drum Hardware.
Strip the 5 bolt "Stuff" off the donor, Proceed to installing on you "6 Cylinder" Spindles---Hell they are the same!
67's ALL were C6OA Spindles, No Difference, and as mccance has stated, you can install the 4 Piston Per Caliper K/H System (Exactly as Assembly Line 67 Mustangs with 428) on those same spindles---I GUARANTEE!!@!!---Have you hear that before???
65/66 WERE Different for those readers.
