This is the set up on one of my 70 Darts. Been on there since 2005 with a set of stock 14" rallye wheels. I would bet that they would fit with the factory 14x5.5 wheels used before 1970 too. The calipers are actually stock K/H 4 piston calipers for a Mustang II and lots of other Fords. Talking about the SSBC kit in post #2
That may be true, I think the 14" rally wheels were the same. I think the K-H disk brake package was the same on many cars in the mid 60's, maybe slight variations.
