No one really answered my speedo question. So, looking over the Nismo catalog I saw that they offered a VSS "kit" consisting of a snap ring and ball, but no info on the gear. Found some old threads and ordered an S14 gear. Needed to dremel out the middle a bit since the S15 output shaft is 3mm larger than the 5 speed. Crossing fingers this works when i finish everything up.
Parts:
32228-RRS50 - Snap Ring
32720-RRS50 - ball
32701-E9800 - gear
