What size brakes?

All right guys I need your help again!!!! I have a 1965 Dart GT and need your help about the brakes on the rear and front. When I got the car the rear end had been changed out to a 8 3/4, axle number 2881489 with Borg Warner Spin Resistant. Can someone tell me what size brake drum and shoe should be used with this rear end and what size on the front?
Went out and measured the drums:
Rear drums: 10 inch
Depth of drum (where shoes comes in contact): 2 inches
Shoes: 1 3/4 inch wide
Front drums: 10 inch
Depth of drum (where shoes come in contact): 3 inches
Front shoes: 1 3/4 inch wide
This does not seem to be right.
