The problem with using Ford calipers is the design of the mounting isn't swap freindly. They're large and bulky, and in many older applications it's part of the spindle which can't be used.
GM calipers are used by the aftermarket because of the ease and simplicity of the attachment. And they work good. They can be adapted by means of a simple bracket bolted to the spindle.
My understanding is the 5 on 5 1/2 rotors used in the straight axle conversion are Ford truck parts from the 70's.
Why couldn't you do something similar with new Mustang parts? New cars use a disk brake hat without the integral hub like it used to be.
All you have to do is turn down your drum brake hub to fit inside the disk brake hat, and fab up a couple of caliper brackets. Then you'll have an all Ford disk brake kit. Camaros use a similar set-up to put C-5 and C-6 brakes on early models. The only problem is you will have to run 16-18 inch rims depending on what model you snag your brakes from.
