    I know on the front is takes the ford backing plates to get the calipers to fit. what can be done on the rears when running 4 wheel disc? I was thinking of just having the brackets redrilled but am I heading the right way or is it even worth it for me to run dual pistons? or just get a set of 4 of ther GM jb7's?

    I built my own rear disc set up using GM front calipers and brackets. The bracket and flange bolt patterns overlapped just enough to create problems, I couldn't bolt them together nor could I space it to redrill. I needed to make up a 1/2" of space to line everything up so I carefully cut down the original flange and made a new one from 1/2" plate. I had the new flange welded to the outboard side of the old one and everything bolted together.

    mid west,
    ive been told that its a good idea to run smaller rear
    brakes than whats in the front, because it helps front to
    rear brake proportioning, thats what im running and it seems to work pretty good, no rear lock up as of yet,
