You would need to make a small tab to connect to the steel panel that supports the grille.




Yep, that's the difference, but if I were given the choice I'd turn a 70-71 fender into a 72 by patching and re cutting the marker hole before adding metal to make the lower panel.

Either way, if you want a direct, no modification bolt on part, the 1972 is on it's own.
