bodyline gaps

Hi all. I am in the process of tearing down my car for a complete bodywork and paint over the next year or two. My 69 Dart currently has a fairly large gap between the door and rear quarter. What should the width of the gap be? I am kind of nervous about it being so large on my car and getting it right. The previous owner had replaced the front fender, so I am hoping he just didn't put it back together correctly...

In the pic attached you can see the door is clearly crocked. I fixed that by adjusting the door post latch. the front fender is also a replacement from an unknown year. I am looking to replace it as well, as the car was hit and the fender is tweaked a bit.

Suggestions and what should the width be?
