How hard is if to swap a 1971 or 1972 dart front end on 1973 dodge dart sport

I know this is an older post but can you tell me more about your swap. Are these all new parts, if so, where were they purchased? I have a 73 Dart Sport and don’t care for the “bird beak” look. I think your transformation looks amazing and I would like to replicate it on mine. Thanks.

I bought the entire front clip from a '71 Dart 4 door that was being parted out, so the parts on my car were all used factory originals. Some, but not all of the parts needed are reproduced. Or were.

AMD makes reproduction front fenders, the front valance, and front bumper.

OER makes a '71 grille reproduction and headlight surrounds

There are a couple companies that make fiberglass hoods, but no metal reproduction is currently available that I'm aware of

As far as I know, the hood latch support panel, hood latch, fender extensions, headlight buckets/brackets, and bumper brackets are not currently being reproduced and you'd have to source used originals. But I did the conversion on my car quite awhile ago and haven't really been looking for some of those parts since then.
