So, how bad was the door before you got hit?
And how bad is the damage?
The driver's door takes so much abuse. Mine was hit as well and repaired by the original owner, and I spent a lot of time dragging the door, kicking and screaming, back to life. If I had the money at the time, I would have bought a new door shell and been done with it already!
My door had cracks around the three screw holes for the latch mechanism, as well as cracks by the hinges, all of which needed repair. My door would not close very well, open very well, or lock very well. I pulled the latch mechanism out, gave it a good soak in paint thinner, and went after it with a toothbrush to really clean it up. Then I replaced all the little fittings on it for the control rods, bought that screw kit with the washers to reinstall, and greased the whole thing up before reinstalling. Now, it works like a charm. I am willing to bet your original mechanism is just dirty and/or out of alignment (due to the screw holes cracking) I also bought new door hinges. You can rebuild the hinges with new pins, and I just didn't think I could do it right so I bought new ones. As it turns out, I did hinge pins on my '90 Mustang and it was pretty straightforward and not as hard as I thought.
As for reskinning the door, I haven't done this, but it looks like a PITA. The pain part would be trying to get the look right in the door jamb, IMO. But I haven't tried it. If the door has been bashed in, it might have "tweaked" the rest of the door, pulled in the corners and what not, and you would need to straighten it out a bit, adding to the headache. I love Mustangs, but I wonder if Ford expected these cars to last longer than a few years? I heard 7 years was the lifespan, and the crappy, flimsy doors is good proof of that theory. Doors that fall apart, yet a drivetrain built to last. Go figure. But I digress.....
