0660.46.020 - This gland nut assembly is used from 1979 onwards on all bevel drive twins for both the bosch pickup wire [left side] and alternator output wire on the right side of the engine. Also applicable to the right side on roundcases or left side on singles. Included is the actual brass gland nut, 1 rubber grommet, 1 aluminum crush washer and the plastic threaded outer nut. Yes the original ones made 30 years ago were both plastic. Ducati started making the larger nut out of brass and painting them black sometime in the past, these are them.
