Here's an old e-mail that I sent to Jim White from the list....

Jim,

Here are some pictures and some old e-mails from Tom W. I
*think* the deal is this.....either way you need the 94/95
knuckles. If you use the 96 upgrade rotors and 16" rims, you
need to modify the mounting bracket as outlined below and in
the pictures. If you use 13" rotors you need 17" rims and you
don't need to modify the mounting bracket at all. I may get
two sets of mounting brackets and modify one set for use on my
spare 16" rims with track tires. Then have an unmodified
bracket for when the 17's are on the car.

Kurt here are a couple of pic's of the 96/PBR brakes.

Kurt- I modified "Cobra" mustang brackets- the mounting holes
have to be
moved .700 and the brackets have to be milled a little to
center everything
on the disk. I am going to temporarily reinstall the 96/Cobra
setup so I can
run slicks on my slicers at the drags on Friday- I'll measure
stuff up and
take som pic's.

Kurt- I moved the holes .700". On the face, I milled off about
.050. (about flush with the bracket) What you want to end up
with is the bracket centered over the rotor. The notches on
the bottom (clearance from the knuckle) can be eliminated if
you mill the brackets off on the bottom through the middle of
the origional mounting holes. If you need better pictures or
measurements let me know.
