I have 35" tires and was installing my tailgate support bracket but while doing so I happened to drop a washer into the screw hole of the tailgate. Since it fell in and I can't get to it I decided to keep on going. Now that the setup is complete I can hear the washer clang around every time I dive over the slightest road imperfection and it's driving me nuts. Is there any way for me to open up the tailgate so that I can retrieve the washer? I can't seem to really find a way.
