You are correct sir, these are non-finned. The 10" brakes coming off are SBP and only the 1-3/4" wide versions. I do have an entire setup for the 11x2. The drums can be turned and I will get a full rebuild kit for it.
@maddawg57 what year/model van did your 11x2 drums come from? The local parts guys can't order anything if they don't have year, make, and model.
That I am not sure that part was done when I got the car. Narrowed Moser, rear van drum setup, line loc, dual master cylinder ,and adjustable proportioning valve were already on it . All I did was the front disc swap.
