1963-1964 Corvette Grille U-Nuts


  • Set of 10 u-nuts
  • Original GM Part# 3831934
  • Includes “M” logo on each u-nut


1963-1964 Corvette Grille U-Nuts

Part number 3831934 Nuts were used in 10 places on the 1963 and 1964 Corvette at the perimeter mounting of the grille. Nothing like the original was available until now. These exact reproduction u-nuts are visible when installed on the car! ¬†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.
