Does anyone have a pic of the lower door rubber? I'm having a hard time figuring out where the two corners are supposed to line up. When I pull then out where I think they should go, the door does not want to close

 

I replaced the rubber on my 55 f350 a few weeks ago. You have to set the weather stripping where you think it should go and then adjust the door strikers as far out as the will go. Keep the door shut for a few days then move the strikers in a little bit more. Keep door closed at this point for another week or so and repeat this process until the new weather stripping has compressed enough to stay at that point. You just have to keep adjusting the strikers till the door closes as it is suppose to. I'm still adjusting mine and it has been almost a month. Each time the doors are lining up and in better, just give them time.
