8 3/4 Rear End Brake Shoe Help

I never bothered to measure the rear drum "overall" width. I usually measure the "wear" area. If you are measureing the total width, across the full width from the outer edge to the mounting area, that has to be more the 1 3/4. If you allow a 1/4 inch on the inside, and a 1/4 inch on the outside, that would give you a drum measurement of 2 1/4.
