I'm rebuilding the rear brakes on my '68 GMC C1500 and I picked up a new set of drums at the local auto parts store. Got them home and noticed they weren't a match. The originals have an additional 3/8" of backspacing over the new replacements. Searching for the correct part online, it appears that the new drums I got technically are the correct drums for my truck, but obviously not for the axle that I have. Any idea what year/make/model I need to be searching for to get the correct drums? The only identifier I can find anywhere on the rear end is the Dana 44 marker. Nothing stamped in the axle itself.

Thanks
