So, quick follow-up - when I compare where the threads would engage (even if one on the left is turned down and threaded properly), it would appear that the correct 72 sender on the left would extend significantly further into the head than the aftermarket one. Looks like the aftermarket one on the right doesn't even have a probe that sticks into the water stream, but that may not necessarily be required. I noticed that the brass is all one solid piece (otherwise this probably wouldn't work...) so, once turned down enough to cut new threads, is the remaining probe part that is inserted into the head first turned down further to clear the hole? Is it shortened too so it doesn't stick in too far? Just curious.
