Who has Dr. Diff 8 3/4 rear discs?

cudamike13 has the 11.25" kit that uses Ford Explorer calipers and they do have a drum emergency brake set up inside the rotor.
Mopar 11.25" Rear Disc Brake Kit

huh, well look at that. I didn’t realize DoctorDiff had a new rear brake kit out, used to be just the 10.7 or 11.7’s and those both used mustang calipers. Yup, that 11.25” kit definitely uses a drum brake.
