1965-1967 Corvette Side Exhaust Cover U-Nuts 3880494

Factory side exhaust equipped cars used a special u-nut to attach the side exhaust cover. Our 1965-1967 Corvette Side Exhaust Cover U-Nuts 3880494 are an exact reproduction of the originals that were ONLY used in 7 places on each side of a factory side exhaust car. Note the “M” logo on each nut. Judges look for these! Get those extra points!

The front bracket of the exhaust cover attaches to one inside the wheel well area. Six more are also used on each side. They are unique as there was no other application in the GM parts system for these items. These are new reproductions of the original part. There has been no correct reproduction of these nuts; just a generic version u-nut that has a hex steel nut instead of the square nut like the original.
