I might do a little research for you if no one answers. Heck, I'll do it anyway, I'd like to know the answer. I have an old drain plug and I work at a hardware store that has a thread size check board. I won't be back there until Tuesday however, four day weekend you know.

Was digging around last night, but could not find the specs. Probably the same luck the other 34 are having (plus yourself).

This seller is Jim B at Wendle Nissan Spokane, WA. Found him to be more then helpful.

So, both parts are stocked some place in Nissans warehouse system.

I think i found it... I think it's a 16.4mX1.33 ... sounds like an oddball size... i was hoping it was a 16M X 1.5, (there's an adapter for that size)... oh, well.. I have an extra plug... might just try tapping a 1/8 npt thread in that... I just don't want to mess with the oil pan if I don't have to... (putting in a oil temp sending unit in)

That sounds right. I just took my pan off to replace the gasket. My thread gauge didn't match with either 1.5 or 1.25 pitch, both were close but not quite. and it was bigger than 16 mm, but smaller than 17 mm. So I think you've got it figured out.
