10 inch Drum Brake Backing/Dust Shields

I'm sure you can use almost any year 10" backing plates up to about '72? The shoes should be 1.75 wide, same as 8.75 small bolt pattern. Drums are the same too.
Hey 65Val. Yes, on the Small Bolt Pattern. I thought I had a ten inch set, but the backing plate mounting on these have 5 holes as opposed to the 7-1/4 has 4 mounting holes. I think the center hole is the same diameter, but I will see tomorrow. Thanks. Old Dart 66
