Quoted from Coyote:Not quite sure what planet you're from, but WMS specifically added a leveling screw/spring to the bottom right mount just for leveling. It is often necessary, since the posts and side rail's heights may not be exactly matched.
My bad. I wasn't aware of this screw/spring. You learn...
