Thanks for the help everyone!
I went ahead and made an updated version of EuroDat's spreadsheet with links to where I was able to source OEM Nissan parts so peope can copy the part numbers instead of transcribing them from the screenshot. I didn't get everything on the list, and some of them may not pan out (the ones from Amayama Japan / Part Souq, specifically) but I have a ton of this stuff on order. I'll let you know how it goes.
