The Tangerine Machine; '75 Dart Sport

Alright everybody, I've come to you for help once again.

The time has come where I've gotten restless and would like to do more changing to my car .
In my mind I think it SHOULD be a relatively easy swap, but I wanted to come here just to double check and hopefully get someone who's done the swap before .

I would like to convert my 1975 Dart Sport clip to a Demon front clip. Fenders, hood, grille, valence. I wanted to know what problems I might run into while doing this conversion, if any.

Any help would be appreciated .
