The only problem with that is, once they go into a dealer, they are lost as far as Nissan parts guys can look. They can do requests and if inventory has been done correctly and they are hooked into the new network, they can see parts. But there is always the chance of parts sitting in rooms and warehouses just laying stagnant.
A few months ago I saw on ebay were 91-92 SE-R front and rear seat skins, brand new OEM style. I know of another member that works at a Nissan dealer that happened to find brand new, OEM NX floor mats laying around. It can happen so not all hope is lost, but man you have to be in the right place at the right time. It is hard to find OEM parts and gets worse every day.
