Mopar 67-72 Kelsey hayes 4 piston calipers

Excellent post! Hubs (aka knuckle or spindle) are scarce. The only hub that works with the OE type K-H calipers are the OE disc brake hubs. They are hard to find.
Not sure about the hubs, but Ford also uses K-H calipers that are the same as the Mopar ones.
