1963-1967 c2 corvette convertible & 1968-1974 corvette all fuel / gas filler neck.

Reproduction of original gm part number: 3923690.

Fits: 1963-67 convertibles; 1968-74 all.

Note: this filler neck will also function for 1971-1974 models, but does not have the restrictor ring which prevents fuel splash back and restricts fuel capacity to 18 gallons. therefore, using this on 1971-1974 models will increase fuel capacity to 20 gallons.
