If you go to the 'other' Datsun forum, you'll see I've got a thread going about Nismoparts ;)

Part of my issue with them is that their site is jank as can be, and they don't mention what parts are meant to fit what A-series motor. That nismoparts site is part of why I started this thread...I think most of that stuff they have listed is meant for A12s, and I don't have one. I'm not sure if all that will fit.
