74 Hood on a 73 swinger???

The Dart and Valiant fender are different in the front also. The Dart fenders are flat in the nose whereas the Valiant ones have a slight peak so headlight bezels/grilles won't fit right. If you swap a whole unbolt sheet metal front end, you can use any '67-76 A-body as a donor. There will be some minor mods needed....wiring, bumper mounting, side markers, mouldings, etc. but nothing too serious.
