Side cover frame tab repair
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
This frame tabs to which the side cover are secured (via knobs) are threaded to 6 mm × 1 mm. Sometimes these threads become damaged beyond repair and and the side cover can no longer be properly retained. A person could always weld nuts to the inside of each frame tab, but that may ruin your existing paint or powder coat. There are a couple of non-weld repairs that work very well. I extracted some of this information from Charlie Mullendore of Antietam Classic Cycle off of the Yahoo! Loopframe_Guzzi news group. In Charlie's own words:
Slip atapped hole clip-on nutonto the tab and use originals or Mark E.'s reproductions. You should be able to find the clip-on nut at a good hardware store. My local Ace carries them. McMaster-Carr part number 95210A150.
