We don't have a lot more detail on this one beyond the tooth count and the years noted in the catalog. If you're rebuilding a box from this period, this is worth having someone confirm against your actual gearbox before you buy, since gearbox internals from bike to bike in this era can differ in small ways that matter.
Give us a call with your frame or engine number handy and we can help make sure this is the right gear before it goes in the mail.
