John,

You really should have posted that to the group, not directly to me. There are lots of group members who know the finer points of the TD a lot better than I do. I'm replying to the group so others can pitch in.

If I remember correctly (which could be a problem):

Early TD brake drums are separate from the hubs. The countersunk machine screws are to make sure the drum is centered on the hub, and to hold the drum and hub together when the lug nuts are removed. The ends of the countersunk screws are peened over after assembly, to prevent disassembly. According to the TD/TF Workshop Manual the drum and hub are not meant to be disassembled.

Later TDs have one-piece hubs and drums.

As far as I know the two types are interchangeable, but you should ask the TD experts in the group to make sure.

If you're talking about the front hubs, the right-hand side has a right-handed thread, the left-hand side has a left-handed thread.
