The aluminum GM rear drums save about 5 pounds each vs. cast iron. I have seen iron with stamped steel around the perimeter as well as the center, and some that were all cast around the outside, so the weight saving will vary. I have even used the aluminum ones on the front of an A body with X body (Nova, etc.) hubs that had removable drums. The 2.5" wide shoe hangs out a little. I'm glad I scored some aluminum drums when the pic-a-part yards had them.
