When I looked at the photo the backing plate didn't look good to me. I don't think it's the one year open knuckle, drum. Just because the backing plate looks funky, but then again the pic is a bit fuzzy. Here's a pic of the exact same front left. Open knuckle drum 44. It's an HD, but who cares, 8 lug 1/2" tube or whatever.
I couldn't give the axle away when I swapped. I pulled the ring and pinion and took the rest to scrap.
Anyhow, see the backing plate fits neat into the drum.
