62-65 early model speedometer gear Chart?
With apologies to the OP for a minor hijack along these same lines.
Has anyone used one of these to calculate gear tooth count?
It comes up to 41 tooth... Which based upon the follow-on charts is accurate as I've used navigation apps to track speed and compare to tach.
Seems off to me. What am I missing?
