I just got a new sissy bar and luggage rack last week. Everything installed fine except for one of the bolts that goes into the fender doesn't want to go in all the way. I tried hitting it with some WD40 and went and bought another bolt and it still won't go in all the way. It seems plenty secure with the 3 bolts tightly fastened and the 4th tightly fastened but not in all the way (it goes in a little more than half way I would say). It's one of the long bolts. Do you guys think this is secure enough and do any of you have any suggestions on how to get the bolt to screw in all the way?
