dart doors

Most of the stuff has already been touched on. The door shells will bolt right up, no problem.

Everything inside the doors- the window glass, window hardware and mechanism, door and latch hardware etc is different. Basically, if it’s inside the door you can’t swap it. The door handle itself and lock mechanism are about the only exception.

The interior panels are different, as are the interior handles and pulls. And the earlier doors have the wing vents, although that may be the point.

So, if you take the complete assembled door as a whole you can bolt them up. The interior won’t match exactly but functionally they’ll work.
