My "new" '74 Duster- or why I need a project like a hole in the head
This whole process is pretty straightforward. Remove the axle, pull the backing plate, install the DoctorDiff caliper brackets.
Reinstall the axle, slide the rotors onto the axle, and install the calipers onto the brackets. Making sure to shim as needed to center the calipers over the rotors. Then add the brackets for the brake lines, and put an extra bend or two on the axle hard brake line. I sprung for new parking brake cables as well so I wouldn't have to mess with the old ones or them being the wrong length, they're installed in the pictures.
The hard part for all of this was I decided to ditch the stock proportioning valve entirely and replace it with an adjustable prop valve. That meant bending a couple new lines. I made a new driver's prop valve to brake line, and just added a coupler to extend the rear line. The passenger side line was long enough I was just able to re-bend it. I also made a nice bracket and mount for the new prop valve to put it in a spot I could reach easily. And bent up some new MC to prop valve lines.
