This is a New Original Nissan Clutch Disc I acquired in a Nissan Dealership Obsolete Parts Inventory. Nissan Part# 30100-09403.  Unfortunately I don't have the Nissan Parts Catalogs so I am unable to give you the years and models this fits. I can tell you it is 20 Spline, 7 1/4" Diameter With a 1 1/8" Disc Surface. I believe based on the age of the other items I have from this stock that this is Mid 70's to Early 80's. The Original Nissan Box is Aged and Worn, but the Clutch Disc is New and in Nice Condition. FREE SHIPPING IN THE US.
