Tail light bracket to fender gasket
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
Moto Guzzi never used a rubber gasket in this location. However, I like to use one there, especially with fresh paint. Here is a pattern I made for the rubber gasket that goes between the tail light bracket and the fender. 1⁄8 inch thick rubber material works great. An old chunk of inner tube will do, though I prefer thicker material.
