Re: Door adjustment on a 69
It is not uncommon for the doors to be twisted, which leaves a the back of the door sticking out about 1/8 to 1/4 at the bottom when the top is flush with the quarter. My factory doors were twisted. According to the pro body guys on here, the aftermarkets doors are even worse.
I am guessing you shimmed the doors out at the top front. That will definitely make the rear gap look correct. Only problem is, now the door sticks out farther from the body at the front than it was designed to do. So, when you hang fenders, you will be tempted to elongate a hole or two and really shim out the fender at the top to line up with the door.
Now, here is the real problem. If you "over shim" the fenders out at the top, now you will have too big of a gap between fenders and hood. It isn't like you can stretch the hood. Not only that, but you will never get the window to seat in the weatherstrip correctly.
Where the hinges bolt to the body, the nuts are captured, but allow for some movement. If you can't get your rear gap good within that movement, you need to get the twist out of your doors. Ask me how I know.
