Rear Brake rebuild?

Thank you. I'll definitely do one at a time looks like things could get a little confusing lol

The 8 1/4 is going into the car replacing the 7 1/2. One side was all good but the other seemed to be run to the ground. Brake shoes were ground down to metal and ate a lot of the drum. Really had a hard time just getting it off and in the process bent some things.....:(
