Catalog appearances for this one run 1971 to 1972, so it's a switch tied to that window in the electrical system layout rather than something that carried on unchanged for years and years. If you're matching this against what's currently on your bike, check the switch body markings and the wiring plug configuration before ordering, since electrical box components changed across those model runs.
We don't have more detail on this one beyond the figure placement and years. Call the shop and we'll confirm fitment before you order.
