I have Dynacorn repo doors and one front fender and there were still a lot of issues. I don't think anything fits like original metal. Though it could also be that expectations today for perfectly lined up panels might also make people disappointed. I've seen many factory fresh trucks in old photos and you can see the panels aren't perfect.

You can't beat that 20% off deal! I would buy a couple thousand bucks of stuff every year for my truck.
