aint nuthin about a scooter but I could use some help. just got a new to me 05 GMC 2500. my driver door seems to be out of adjustment. the gap from the bottom to the top is a lot narrower at the top than the bottom, and I get a lot of wind noise. are these doors adjustable? can't seem to find but one bolt that might be the adjustment bolt but not sure. anyone got any knowledge on this?
