Many dealers added the "custom" pedal trim and other interior options to stock FGFs as the buyer wanted. Thats why you'll find many original FGFs that are Stock but have quite a few 36-38 year old custom interior pieces in and on them. Mine is one. I am now trying to add all the custom interior options just so everything matches.
