You are looking at NOS GM rear bumper, pt# 358333. This is the wider style rear bumper without the rubber impact strip. Correct for 75 to 80 Monza Sunbird and Starfire notchback or….. hatchback models with single headlights. Look at your car before buying. There are a few really light storage scratches that will buff out (see 4^th pic). Otherwise, still mint. On a scale of 1 to 10, the appearance is a 9. NOS is the best there is !!!!
