Dual seat rubber pads
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
Moto Guzzi originally placed some nice rubber pads between the frame and the dual seat. The rubber pads were square and fit over the three vertical tabs that index the seat to the frame. These pads are not referenced in most of the spare parts catalogs, but they can be clearly seen in the early V700 spare parts catalogs (MG# 12461600).
The purpose of these pads is to prevent the seat pan from rubbing directly on the frame. A nice touch that was later eliminated for cost savings reasons, I'm sure.
