New Moto Guzzi Door Mats Available Now
The fender brackets could prove to be a pita to find and fit to the actual fender....and won't look great IMHO.The LM lowers just have two suds machined into them on the inside so maybe consider that .Like Guzzista said SP ones would be a straight fit and should be findable in the US.
If the bosses are there, then Sacko could drill and tap the fork lowers to mount a fender, perhaps?
