Dart Sport to Demon Clone

There’s a “how to” on the tail panel swap

Duster to Demon Tail Panel Swap

‘73’s didn’t have shock mount bumpers so the bumper swap is easy, there’s nothing to do in the back beside the tail panel.

The interiors are different, you’d have to do a door swap if you really wanted the earlier interior. The rest of it can be worked around with some minor tweaks, but the doors are a major ordeal unless you do a swap.

The rest of it is pretty easy. I turned my ‘74 Duster into a ‘71 Demon tribute, my build thread is in my signature.
