NOS, OEM 17 tooth (black), speedometer pinion gear assembly, pn 32703-78101 (includes NOS carrier)
Original factory packaging has been lost so will be mailed with out that, but it is a brand new, never used, assembly.
NOTE: This part came stock on virtually all 1970-1989 S30, S130 and Z31 Z car models as well as 200SX and probably some other Datsun & Nissan models of the period. The 17 tooth gear should be matched to a 3:54 ratio differential to cause speedo gauge to display correct speed.
