Actually the calipers from 68 to 73 are the same, 68-69 disc spindles are the same, 70-73 spindles are slightly beefier and take a different rotor(larger wheel bearings I think for the spindles).You will find Fairlanes of the same years with the same brake styles per mentioned the Mustang years.And don't forget the Mercury intermediates as well.One thing many people don't realize before doing granada swap, is the caliper and caliper mounting style is totally different from that used in Mustangs 68-73, and is easy to spot.I always think best alternative is to find the 68-73 stuff, at least visually they look nearly the same.
