Nut to secure dash rubber isolator mount (MG# 92750062)
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
A special nut is used to secure the rear middle dash rubber mount. The nut is longer so that it can be much more easily fastened in place. Harper's Moto Guzzi has them available. Were I to need a generic replacement, I would likely choose McMaster-Carr part number 93590A106.
