This information could help (from challengerspecs.com)
Drum brakes were standard and measured 10 X 2.5 inches front and rear or 11 X 3 front and 11 X 2.5 rear on the R/T.

Optional front brakes were 10.75 inch vented discs with single piston, floating, pin type callipers. These discs were of a two piece design which tended to warp with heat under (very) heavy use but returned to normal after cooling. This problem was not put right until the start of the 1973 model year.
Where front disc brakes were fitted the rear drum size was 10 X 2.5.

The information is contingent upon the type of car RT/Non RT with drum brakes. Go to Rock Auto and they list the kits for drum brake cars. Look at the applications for each kit listed. It should answer your question. I believe the hardware for 11in drums should be the same for front and rear. Only difference was the width (3"vs 2.5") from front to rear on an RT drum car.
