You will need to graft the tail section from a 70 or 71 Dart due to the trunk opening being revised from 69, as well as the bumper attachment points. I knew one person who did it with a 68 as a starting point 20 or more years ago, but I only saw it after the rear section was grafted on. There is also a member on this site who lives here in Alberta that has a very nice example, complete with a 426 Hemi and a shaker hood. Have never seen it in person and I don't recall his screen name. Sorry, I know that's not much help.
