I have a '65 2500 panel. I am having a hard time finding a replacement drum for the rear. They are 13" brakes like a dually would have:

However, I don't have dual rear wheels, and my drum is only 5.18" deep. The only drums I can find are for 12" brakes, or the bigger drum like I need, but for dually. It's hard to tell, but I think the numbers on the drum read L651 H 48716. Can anyone help me here?
