1969 Dart GTS340 on the way
Welcome to FABO. I believe the correct color is turquoise, but the swinger guys should be able to confirm this, (George R, Skipsdart, Etc....). Sounds like you have a mostly original car. I don't believe the remote pass side mirror is correct, but once again someone might chime in and correct me or confirm you.
Good luck with the car and can't wait to see pics.
