Drop the other bolts, let the board hang loose; may give you a bit more room and/or better vantage point. Good to know about that; I hate my boards and want to upgrade to power steps.
I'm gonna edit my post a bit. Can you snap some pics to clarify? Do you mean the bolt that attaches the mount to the truck itself, or the bolts that attach the step to the mount? I found this; it shows how the OEM steps install, so it may be of some benefit
The way it mounts looks pretty crappy to me.
