old qr is cut off and the potts mod qr fitted
the adjuster is different for a front as well rob
both the above parts are available at porkchops
alternatively just cut off the qr and fit a cable guide. take off the adjuster and set it up as you would an fs880 caliper
you will need a longer spindle as well
get a bulldog front for 9.99 and swop all the parts maybe
