Hey guys, I'm overhauling my brakes tomorrow because I need a new Master cylinder. So at the same time I'm going to replace my rear shoes. I went to Napa and they said they had 1.75" and 2.50" shoes available. Any ways to know what size they are without taking it apart first so I can still drive there to get them? It is a '74 Maverick Grabber, front disc rear drum, manual brakes. Thanks guys, ~Brian
