4. Loosen bolts (D), (E) and rear nut (F).  move bailey weatherstrip outboard so outer nylon pads are in contact with door outer panel reinforcement.  Retighten bolts (E).  move glass run channel so the top of the glass is .58 from the vertical flange of the roof rail (move the glass run channel outboard to move the upper edge of glass inboard, move the glass run channel inboard to move the upper edge of glass outboard.)  Retighten bolts (D).
5. Turn adjusting screw (G) so the front and rear inner nylon pads are in light contact with the wedges.  Tighten nuts (F).
