What would it take...

to 're-body' a '73-'74 Duster into a '70-'72?

I mean, beyond the obvious - tail panel, fenders, hood, grille, bumpers. Are there different brackets for things, different mounting points etc.

Just curious, got to thinking about it since the later models seem to be more readily available than the early ones. Plus they tend to be a little cheaper.
