8 1/4 11" "A" body (only?) rear drums

If you're looking for the 11 X 2 rear drums, they only came on low end '65-75 C-bodies and '65-71 1/2 ton pickup trucks. The part number has been superceded through the years but here are some of the factory numbers. 3004746; 3004932; 3549843; and 3780526. There were 3 different manufacturers so try to get them in pairs as they have different heat disappation characteristics and might have a tendency to pull to one side when hot, if you mix them.
