I am restoring a 1968 250S. I'm looking for the original left rear quarter panel moulding. The original part number is #108 690 1780. I am aware that there is a replacement part for this moulding with the part number #108 690 1980, but that is not the one that I am looking for. The original part was 3 pieces: rubber backing, chrome moulding and 1/4" rubber bumper in front. The rubber bumper and the chrome moulding is half-wrapped. The replacement is only 2 pieces. Please advise. Thank you, Stan
