Grille Help!!

Ok guys here's what I got going on. I got a 72 Demon grille for my 72 Scamp as I did not have a grill for the Scamp. A few weeks ago when I got the grille I just put up till I had time to get to it. It's in great shape, just needs a repaint. As I started to get to work on it today something just wasn't right. So I lined it up and it was not even close to being right. The grille is marked 72 but it's to tall and all the mounting tabs a wrong. No way it will fit. The guy I got it from swore it would bolt right on. So now I have a chance to get a Dart swinger grille now. Will it work? Or should I just try to find a good Scamp grill.:banghead::prayer:
