'73 Dart Sport 340 4spd: $33,000?

I'm looking at the car thinking that I hate the beak Darts, but the black and red stripe I could actually own that thing. Well the price is crazy, and that cluster that came on old A-bodies that never made to the 73's?
Could you add a cluster like that to my 74 Duster and it work without hacking up the harness or the dash?
