I bought an '86 150 for my Christmas present to myself. The weather seals are in good condition but the doors are a little loose when closed. There has to be a way to tighten them but I don't know how. Any help will be appreciated.

 

you probably need new door pins...

 

Ur Striker on door is loose or the plastic on it needs to be replaced. about 4 bucks at the most at ur nearest auto parts store. ur going to need a torq wrench for the torq screw. real easy to fix and replace.
