I'm not familiar with mopar, but you might be able to reform the top front of the door to match the cowl, if its not too far off and fender fit will allow it. Or you could weld a bead down the back edge of the door.
Could a weld bead on the door edge also fix the body line, along with Adtech P17 down the door for an easy shift in the line?
