Front bumper cover interchangeability

Hi guys,
I'm need a bumper cover for my 1995 RMW.
Are the RM sedan (or any other B body) bumper covers interchangeable?

Thanks

Sedan covers won't work, the only covers that will, are RMW's.

The grille is taller on the RMW than it is on the Caprice or OCC. The bumper is cut to fit under the taller grille. The support for the grille is also taller to match the grille. The other bumpers will bolt up to the RMW, but the grille, and support must be changed to match the bumper cover. The bumper support is also shaped to conform with the bumper cover, and the other covers would have a tendency to sag through the center, if you do not also change the support.

The RMS is a totally different animal.
