I've got a set sitting on my shelf, so you don't need to do it.
HTe 240-Z drums will fit TR's with 9" rear brakes. This includes
most TR-4's, 250's and 6's and some TR-3's TR-2 and some TR-3's
had 10" rear drums. The Datsun aluminum drums need to have the
center hole enlarged a bit, but the bolt pattern is the same. If
you want to retain those little drum hold-down screws, the holes
for them will need to be drilled and countersunk as well. The
backing plates of some brakes will foul the inner edge of the
drum, so the drum may need to be trimmed there, too. Test this
first, though, as they don't always need to be trimmed.
later,

I saw some beautiful finned aluminum brake drums on eBay recently for the
rear of the tr3. The seller said they were off a 240z datsun. Does anyone
know how to mod a pair of these drums to fit the tr3?

Problem solved. The drum is definitely not a Triumph drum. Probably an MG.
Stupid me forgot I had a TR4 sitting in the corner that I could pull a
drum off of. Definitely a difference in drums.
So now to get the Datsun 240Z drums modified to fit and I'll move onto
the next problem.
