I found a pic of my small bolt pattern rear backing plates...does yours have the five bolt holes in the center? Bad pic, but it will work!
yeah..compare it to my pic...you see those 2 lumps..you have the ruler in front of one...th one just underneath it has a hole that looks like where the emergency cable would go...all right i think we've established it is a rear backing plate..but where do i find 1" x 2.5" shoes,wheel cylinders, hardware...and can't for the life of my think of the adjuster thing at teh bottom
