Needing stock 8 3/4 10x1.75 sbp drums

I bought a Centric set years ago in 10". They were SBP. Only thing I modified was where the hole for the axle register is on the outside of the drum, it has a slight rise in the casting. I ground it flat so there was no issue mounting the wheels. Not sure if this has since been corrected in the design.

Some big auto parts stores may be able to get them to you as well like AugoZone, ...
