Rear brake drum problem

I may be wrong,, but I'm pretty sure, for rears, if you've got 10 inch brakes the shoes come in 1 3/4, or 2 1/4 inch. (they only come in 9, 10, and 11 inch )..

Measure across the diameter of the drum, for 10, or 11 in. , then measure the width of the shiny area, your old shoes rubbed on,, should be approx. 1 /3/4, or 2 1/4 in..

hope it helps .....
