If you are talking about the rear bolt that also attaches the rear fender my best advice for a long term solution is the "bag drop kit". I think Rattlebars makes it {somebody correct me if I'm wrong} & it works great. I put it on both of our bikes. It's a bit pricey for what it entails but it makes life MUCH easier when you need to drop the bags for servicing or whatever. Lining up those fender bolts is a sucky job!
