need help with brake drum I.D

we just got done painting the walls of the garage today and going to paint the floor tomorrow night. Going to figure out the layout tomorrow and install the black pipe. Then it is time to get started on some cars. Thanks again for the memory. The Duster is back together and the number of the brake drum is on the top of my list of parts for this car. I will not forget that number and don't you either in case I do. LOL.
