wes, If you are not already aware of bikebandit, they have an online parts fische that you can reference. Three things to remember about them though, the part numers are their own system, not Triumph, orders for Triumph parts take a loong time from them, and their customer service is not as good as other online vendors. But is is a good resource for us.
If this is not your correct vin/sn, you can correct the selection.
