Mopar 9 1/4" rearend

Have a 9 1/4" 3.55 Posi unit I recently picked up. Has anyone had any experiences with these rearends in the Dart? By that I mean, once the unit is cut down to fit the car, what options might I have for disk brakes? I've not seen anyone offering conversions, so any links or suggestions would be very welcome on my end. Thanks in advance.
