A 70 dart would have the bumper with two tail lights but so should your scamp unless someone changed it to a 71-72 dart bumper but to have the correct bumper for the 70 your gonna have to find a two light bumper. Also yes the fenders are different your gonna have to find 70-71 dart fenders for yours or 72 fenders and change the side marker light if it has to look exactly like a 70. For the front end swap your also gonna need a 70-72 front valance. Good luck Justin
Of course you can always do what you want, it's your car, but I think the Scamps are the best of both worlds. You get the Duster front clip with The Dart body.
do you think that the 71 plymouth scamp dash will be legal? did any darts have the same dash?
seeing as rallye dashes never came in scamps to begin with you would need to find a complete dash w/ ralleye gauges and frame to use in the scamp. if you want a rallye dash in the scamp you will have to take the complete dash frame out you have now and basically start over with a rallye dash frame to make it work. then you will need to get the correct wireing harness to connect the new gauges in the dash. what you are talking about doing is all possible , but it is a major undertaking that is going to take a lot of time and money. it was said earlier that there are not many scamps out there and this is true. you would be a stand out in a crowd if you kept you car as a scamp, and miles ahead it time and money spent as well. add some scoops and drop a 340 in it and let it go!
