    13-7 1958 BUICK FRONT DOORS (SERIES 40-60)

    The 1958 Buick front door hinges are the swing-out type with an integral check and hold open, similar to past models. At both the upper and lower front door hinges one of the hinge to front body hinge pillar attaching bolts is installed from the front of the front body pillar necessitating detachment or removal of chassis parts to gain access to the bolts for removal of the hinges from the body. However, these bolts have a hexagon end and can be loosened from inside the hinge box thereby facilitating adjustment of the door hinges at the body pillar without removal of chassis parts. The 41 and 48 doors have a removable door window frame. All doors are equipped with a waterproof door inner panel water deflector which is cemented to door inner panel. The bottom edge of the deflector fits into a slot along the bottom of the door inner panel thereby deflecting any water into the bottom of the door where it can drain out the door bottom drain holes. Door lock levers are provided with spring clips which facilitate detachment of the connecting rods.
