New Moto Guzzi Door Mats Available Now
As you can see, the smooth topped one also has narrower spacing between the fork tubes, must be from an LM. My T3 has LM style clip ons, and so had unused bar clamps on the top tree. I ground off the lugs, welded up the bolt holes, and polished it up. No big deal, came out nice. If you'll do the grinding, I can weld it up for you for nothing.
grinding on aluminum is not recommended. sanding or milling is better. the aluminum can clog the pores of a grinding wheel, overheat, expand and crack the wheel while spinning at high rpm. a hand held die grinder with a milling bit or a belt sander (my Dad's shop used to have a ferocious one called "the beta") are my prefered method. Save your self a bunch of grit. Saw off the lug as close to the clamp as possible, then remove via your favorite method.
