The gearbox plug is just ordinary NPT pipe threads, so any plumbing supply should have them.  I forget the size offhand, probably
3/8".  I get mine at MMC

But I prefer the steel magnetic ones rather than brass.

I don't believe the diff on a 72 TR6 originally had a drain plug, so you may need to investigate what was added.  I don't know why
anyone wouldn't use the same as the gearbox, but it's a possibility.
