Gap problems

[sjquinci]

I am working on a 69 camaro convertible. I am trying to line up the seams on the drivers side door. When the door is closed it touches the rear quarter panel (no gap). Its not overlapping, but it is touching. The front seam of the door is a little less than 1/2". I am also having an issue with the drivers side connection between the radiator support and fender. I can get it to fit, but it takes a little muscle. For the door it seems logical to move it forward until the front and rear seams are correct, however the door hinges prevent me from moving the door forward anymore. My two questions are....Can I manipulate the door hinges to move the door forward 3/16"? & Should all these body parts fit with ease, or is it common to use a little muscle to get them into place?
