I have a '71 LWB that the PO added SC flares on the rear fenderwells and then used an SC rear bumper. I want to revert back to the standard LWB rear quarter bumpers but need to flare those bumpers to match the SC flared fenderwells. I have both the LWB rear quarter bumpers and the SC bumper to fenderwell flare extensions (see attached photo). Has anyone out there done this modification and have any tips to pass along before I attempt it?
