The outer door frame can be replaced as a complete service part or vairous segments can be sectioned. Complete service part replacement requires the removal of the roof panel. Sectioning the outer door frame and inner door frame reinforcement is usually much faster and more cost effective. Since the outer door frame is manufactured as a single component, service parts for sectioning must be cut from the service panel and modified as necessary. Sectioning should take place in shaded areas only.
