Where To Find 10" Shoes

Guess I should have taken a pic of the new shoe. The rectangular hole is larger diameter than the original top hole so the loop on the spring has no way to stay in place. That is the only difference in the shoes. Here is an example, notice the top rectangular hole then compare it to the current brakes via the link below.

Check www.RockAuto.com

They show both the round and square upper spring hole for the 73+ 10" front shoes.
The front drums are the "ribbed" type, right?
