Had some trouble installing the signature series sliders today. Drivers side went on perfectly fine with no issues whatsoever. When I got the passenger side up and over the body mount washers, I noticed the center mount of the slider sits about 1/4-1/2” away from the frame, while the other two mounts are sitting flush against the frame. Because of this, the he two bolt holes don’t line up either. Anybody have this problem before?
