The drum should be 10" diameter and the shoes 2.5" wide.

The drums look like they may be for 2" shoes. Youl need to make sure the drums are wide enough, and also not worn beyond the wear limit, which should be on the brake drum.

I thought they were 2" wide from factory on 10" drums?

Here are a couple pics I did not measure. The Mach 1 is Q code and Comp. Susp. and the vert is H code regular 9". I have seen drums without the fins could have been replacements.
Mine were painted on the original car maybe because of the slotted aluminum wheels. I use charcoal grill paint on them high heat resistance. Notice the missing balance weight on the drum. Car never gets driven so I did not worry about it.
The last pic with the broken lug stud is the 73 vert.
