1965-1967 Corvette Side Exhaust Cover Mounting Nuts 3880494


We manufactured the correct u-nut for mounting your side exhaust covers. These are just like the original. They even have the “M” logo!



1965-1967 Corvette Side Exhaust Cover Mounting Nuts

Factory side exhaust equipped cars used a special u-nut to attach the side exhaust cover.  We have reproduced the GM 3880494 u-nuts that were used in 7 locations on each side of a 1965-1967 factory side exhaust car.

The front bracket of the exhaust cover attaches to one inside the wheel well area. 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. Judges look for these! Get those extra points!   Note the “M” logo on each nut.

Remember, we ship orders of $40 or more FREE to the lower 48 United States!
