Not sure where your e-body brake struts came from, but the set on my challenger looked exactly like the 11" ones I posted above. And had a Mopar part number on it just like the flat one I posted above. A little shorter, obviously, but the same exact shape. I've never seen a set for one of these Mopar set ups that didn't look like that. You can go on eBay and search 10" Mopar drum brakes, all the brake struts look exactly like one of the kinds I posted above.
And even if they didn't, the "bent" ones like the ones I posted above fit the 2.5" wide brakes. The other 3 I posted above came from 11x2.5" brakes. I have 6 sets of 11x2.5" rear drums, two sets of 11x2's, 2 sets of SBP 10" rear drums, and one set of 10x2.5's now but I've sold 3 more, they all looked the same. Obviously the 10" and 11" hardware doesn't interchange, but the shape is the same, just a different length.
