Help Please - 8.25 11x2 Brakes?

I pulled an 8.25 rear out of a 73 Duster for my 67 Dart. It's up on the hoist in the shop now and the mechanic is pulling his hair out trying to find replacement pads for it. The drums are 11" and the old pads are 2" wide. He has a set of 11x2.5" shoes/pads but they are too wide for the freshly turned drums. The rear bolted right in with the proper perch to perch distance so I'm guessing the rear is an A-body rear end. Did A-body 8.25 rears come with 11x2" brakes? If so where can I order pads? If not, what the heck do I have here?
