Second gear on the layshaft works with its mating gear on the mainshaft to give you that ratio when you're in second. It's a wear item like the rest of the gear cluster - if you're rebuilding a gearbox and finding chipped teeth or excess play, this is one of the pieces you check.
Our catalog record ties this to gearbox rebuilds in the early '70s range but doesn't spell out an exact model or year fitment, so confirm against your own gearbox internals or give us a call before ordering.
