68 Barracuda Front Suspension Rebuild Kit

The calipers are probably the biggest giveaway, the 73+ are single piston, sliding calipers where the KH’s are fixed 4 piston calipers. Next is the bolt pattern, the KH disks are 5x4” and the 73+ stuff is 5x4.5”. Although the aftermarket kits now have 73+ brakes drilled for 5x4” too so that’s not as good an indicator anymore.

The KH disks use spindles with the smaller upper ball joint and a different bolt diameter and spacing on the lower ball joint too. The KH rotors are 2 pieces, rotor that’s swaged onto a separate hub, 73+ stuff is 1 piece rotor/hub assembly.
