Found a Source for 10” rear drums with 1-3/4” shoe

I talked to the technical group at Centric to verify this number, 123.63044, was correct for the 10" x 1 3/4" drum with 4" bolt circle. The guy said yes and the specs on the web page were incorrect. So I ordered a set from the local parts place after telling him I checked. I just went to pick them up and check the size on them. NOPE 2 1/8" wide drums. They have that exact number stamped on the drum. I will be calling Centric again.
