have to slam door

[chris1htx]

hello all, for the past two years i have been having to slam the doors on my 84. the truck was painted and had new seals installed, i figured after a while the seals would be broken in but still nothing. it is not my daily driver so it never really bothered me but i'm wanting to figure out the problem now. the truck has been set out in the sun so the seals can "form" but still nothing. i figure maybe the doors weren't aligned correctly. i'm nervous to try to realign the doors (never done it before), especially having to rematch the body lines.

does anybody have any idea of what is maybe making the doors hard to close? or is the door alignment probably the main cause?

of course rolling down the window helps significantly with the door closure. any help will be appreciated.
