Ducati Bevel Single Twin Exhaust Nut Tool 250 750 900 STAINLESS Triumph Chassis They bolt between the windshield

They bolt between the windshield itself and the 1350-6840/6940 brackets attached to the forks

Triumph's part number should be 82-4585 or F4585

I believe Guzzi's number for this lever is 1360-6840

These seals should fit just about ALL Guzzi big twins from the mid-seventies through through most of the eighties
