front clip swap on a 68 dart 4 door

Hey guys, this is my first post here so Id like to say hi. Anyways, I have a 68 4 door that Im bringing back to life and I like the way the front end looks but I like the 70 grill and headlights better. Would it be possible to swap to a 70 front end so I can have the grill and lights or are the body lines different? Im trying to remember the car and I dont really remember the lines and its too dark for me to see right now. Any advice or thoughts? Anyone ever do this before?

Thanks, Josh
