Scott Drake Bumper Wave Washer for 1965-1970 Mustangs.
Keep those brand new chrome bumpers in place with these stamped steel wave washers. They are designed to work with the bumper bolts, keeping tension on the bolt at all time.
The wave washer sits on the inside of the bumper, the chrome bumper bolt presses through the bumper and slides through the wave washer. When mounted to the bumper bracket, the wave washer will keep constant tension on the bolt.
