Hello, I got a decent 8&1/4" rear out of a donor 71 Duster that I am putting in a 68 Dart. It has 11" brakes on it so I'm pretty sure the brakes are not original to a Duster. They are 2" wide. All of the listings I can find for older big cars that have 11" brakes are 2&1/2" wide. Does anyone know what these came off of so I can order new shoes and drums? Thanks!
