I know a few years ago there was talk of dual knock outs, one for side fill, one for rear to fit the 66 Fury and 65 Dodge C Body. Hope they do it, I will convert my 65 to a rear fill and place a dummy filler kneck for looks in the gas door. The 65 Fury has a cut out for rear fill, would have to change the license brackrt and a few mods. Hate filling up around nice paint.
