The side door frame openings feature a unique modular build sub-assembly design in order to improve manufacturing quality. The openings are composed of numerous individual components that are pre-assembled and attached to the vehicle as a single unit.

You may replace the door frame as a complete unit. Various segments of the door frame may be sectioned, which is usually much faster and more cost effective. There are some key structural areas where sectioning should not take place. Because the left and the right door frame openings are only available as complete assemblies, service parts for sectioning must be cut from the complete assembly and modified as necessary.
