This lincoln navigaor has had the lambo doors installed. The fenders, running boards and door panels had to be removed to complete the project. The fenders have to be modified to allow room for the hinges . The wiring harness in each door had to be extended 12 in. to allow the doors open fully the lower door moldings also had to be modified. This was our first lincoln navigator installation however we have installed the door kits on several hondasand mazdas.If you have any questions about the insallaion feel free to contact us at 717-295-7263
