78 grill trim?

[raws67]

Well I have searched and cant find an answer to my question. I recently aquired a 78 cheyene that originally came with a chrome grille. Currently it has a tube grill and I want to go back to stock. I bought a 78 grill and I went to the wrecking yard and obtained the factory mounting brackets but while I was there I found a 79 grill that still had the horizontal trim installed. I bought the trim thinking it might be correct for the 78 grill. Am I right? Also what would be the correct colors for the grill? Thanks
