Brakes stickin after brake job

I questioned the rear pads and was told he ordered off the rear end model numbers because it has a Mustang 8 3/4 rear end which I told him. He also ordered the drums from that model which looked different from OEM's. I did not agree with the washers placed behind drum on axles. I watched all day from 10 AM until 6 PM and was tired and ready to just leave because I have to go back for the tires anyway.

Holy Crap.
Sounds too late to run. :-)
