Working on a 72 Demon. Fenders on the car are bad. Picked up a good pair. Noticed that the side marker cutouts are slightly different. One has a V shaped cut on one end of the opening. The other one has a small U shaped cut on one end of the opening. It also appears that the body line below the marker light is more pronounced on one over the other. Can anybody here tell me if there is a difference I should be conderned about??
