10X1.75 Rear SHOES

Jim I'm not positive but I've heard the 10x1.75 was standard size on all the A-body rears. The 8-3/4 in my car is from a 69 Cuda and it has the 10x1.75 brakes. The reason the back ones are smaller is because the front brakes do 65-70% of the stopping so the rears don't have to be as big.
