10” rear drum questions

I have some questions, may be dumb to some. I have a 1969 Dodge Dart swinger with 340 and 8 3/4 rear end with small bolt pattern, 5x4. From what I can tell I have 10x2 1/4 for the front and I from literature I think the rears are 10x1 3/4. Do both front and rear drums the same size? I can’t find any different drums than 10x2 1/4 drums. Any help would be appreciated. Thanks!
