Thank you for the donation.
There are two types of rear axles, single or double tires.
For single tire type, the lugs are on the axle shaft and you cannot replace the drum only.
For double tires, the axle shaft is bolted onto the hub via 6 holding bolts at center of drum. For this design, you can replace the drum only but you need to be sure that the diameter of the drums are similar. If not you would need to replace the backing plates as well.
If you are able to upload some pictures, that would help.
