I have a set of early Z car rails. They are NOS (New Old Stock), part numbers are 74802-E4150 and 74803-E4150. I have had these for about 30 years.
I had a friend who worked for Nissan check the price 6 - 8 years ago, they were no longer available then. The wholesale price back then was in the $750.00 range each.
These would be great for a restoration project, don't think there is another set on the planet.
Asking price is $2000.00.
Local pick up only or you arrange for shipping. Located in south eastern NY, 20 or so miles north from the NYC.
I have pictures on my phone that I can send, can't attach from my computer.
Any questions, feel free to email me.
Dennis
