Can anyone help me with part numbers for a Buick Someone clipped my 1955 Buick Special with there car and cracked a part of my bumper so I am going to have to replace it...this is the inside part attatched to the wing/fender....I have seen a part that looks similar but not sure on E-Bay there is a part number (P/N1166508 ) how can I tell if it's the part I am looking for
Upper Radiator Bar Grill Extension The part number 1166508 LT is the one that bolts onto the left fender that you mentioned. Part number 1166509 RT is the one for the right side. So you do have the correct part number.
