8 3/4 SBP brake options
Was leafing through the July 2015 copy of Mopar Muscle magazine, and found a brake resto article on pages 10-14 by Steve Dulcich. In page 14 is a photo of the OEM 10" drum along with its replacement from Rock Auto. The "hat" portion of the OEM rises at an angle, whereas the Rock Auto version rises straight up. Apparently no difference in fit or function.
Points I take away from this are: 1. Rock Auto has 10" drums for 8.75 BBP axles 2. It may look different, but if the shoe fits, run with it.
