As always now, be ready for crappy quality with non OEM stuff. I was replacing the factory 11"x 2 1/2" finned drums on my '89 Diplomat Police Package and ordered a set of Raybestos from Rockauto. They were so out of round out of the box that when I tightened lug nuts and it pulled the drum in, the rear wheels would barely even turn. So much Chinese junk. I would've had to find someone to turn them which isn't easy anymore, or ship them back to rockauto at my expense. I ended up junking them and buying a NOS set. Expensive but I get 75,000 miles or more out of a brake job and the NOS ones were perfect.
