Well, kinda. I stopped at O'reilly's, they have 10" SBP drums, but she's telling me they use either 2 1/4 or 2 1'2 shoe's, can't remember which, 56 bucks each, one day wait.
those are the exact drums in just bought last week for the exact same application. Changed my 65 dart to 8 3/4 SBP. They work perfect!!!! Should be 5 bolt by 101.6mm which translates to 4 inches. They do use 2.25 brake shoes as well. I used all the same rear brake hardware from my 10” 7 1/4 set up and everything switched over great!
