Our catalog record ties this one to 1970 appearances and it shows up in the OIL PUMP, GEARBOX SPROCKET figure as well as the GEARCHANGE MECHANISM plate, so it's a small but specific piece in that corner of the engine. The description and figure titles don't spell out which particular model it belongs to beyond that.
If you're chasing this part for a rebuild, give us a call so we can confirm it matches what's actually in your gearbox before you order.
