Rear backing plate size?

Hmm. I measured the backing plate and it is 11" and 1 1/4 offset. But the brake pads themselves are measuring 2 1/4 if I remember correctly and not 1 3/4 as stated above. Maybe someone put the wrong pads in? I'm going to be getting a rebuild kit for the front drums and want to make sure I grab the right stuff before walking out the door.
Sounds like you have 10" x 2 1/4" FRONT drums. Front and rear shoe widths are not going to be the same.
