I'm not 100% sure, because of the clamshell headlight in the 1965 wing. But on photos they look the same. The 1965 Riviera was 1 inch longer, but maybe this difference was due to the new rear bumper ?

But the 63-64 had the same design wing, only with the parking lights mounted in the same size pods where the 65 Riv has the clamshell headlights. Check photos !! 1964: 1965:
