If I was to use an original 65 904 or 833 I would not bother to use the ball and trunnion style driveshaft- it would definitely be the conversion setup!View attachment 1715127064
It actually fits a 65 Valiant or Barracuda with the flange on the end for a ball and trunnion 904 or 833 with an 8.75 rear end. They can be made longer for use with a 7.25 rear end or for a Dart with whatever rear end you have. If I were to use my 833 in the wagon it would bolt right in but may end up using a 904 with a regular slip yoke with the 273.
