Trying to help my uncle put the doors on his 68 Dart. Currently trying to install and make operational the outside door handles. Not sure but there seems to be some pieces missing. The door panel is off. I can see a rod inside the door running from the inside handle to the back of the door in what seems to be the same place that the lock knob rod goes down into. These other pieces are loose and came with the car. Door handles, locks, and these rods. Is this all I should need or are there other rods or those plastic clips required? Thanks.
