Arm, Gear Shift Link

The gear-change mechanism, including the selector forks and the other parts of the assembly will, sooner or later, require some remedial work to ensure that the gear-change is accurate and nicely 'snappy' rather than hit and miss with a sloppy, imprecise action. The more parts you can afford to replace with new zero wear items, the better, ultimately, the results will be.
This component and some of those listed below will give you an idea of what maybe required for a satisfactory outcome:
