Are the factory grilles on '70 Plymouth Satellites, Road Runners and Belvederes the same?

I'm building the Monogram '70 GTX kit as a Satellite and using the Road Runner kit's grille, as based on what I saw at www.hamtramck-historical.com , all three grilles appear to be the same, but maybe the small trim band around the grille's perimeter is the only difference?

The grilles in the following two pics appear to be correct for a Road Runner (and maybe for Satellites & Belvederes, too):





TIA.
