Hi shannon. I have not done this myself, so bear that in mind, but I think all you would need is the square bezel and rectangular center pieces from a later a or b Scout. You would need to ditch your round bezels and I think you would also need to remove your center grille mesh piece. Then it should be a matter of careful measurement and creation of the necessary fastening holes into your existing grille frame to accept the a/b bezel pieces. I don't know if the grille frame is bolted in or spot-welded in place, but it shouldn't be necessary to swap that piece out anyway.
