I have the chance to purchase the headlight mounting bracket off a LeMans 4 to replace the broken one on my 3. Does anyone happen to know if they are the same? Per the Harper's website, the Guzzi head light part #'s match, but it's hard to tell from the pics. if the brackets do. There is a part # for the complete unit (light and bracket) on the 3, but not one for the 4.
