Thanks for all the replies...

I checked the door hinges a while back. I had problems with hinges on another project so, I thought to check that. There is no movement in the doors, the hinges seem real good. I also checked the sides of the doors for marks that might indicate that the bolts were hitting somewhere. didn't see anything but, if they should be flat head screws I will change them regardless.

The body lines seems to be fairly close. The body line above the door handle matches up with the one on the corner of the cab.They were way out of whack when I got the truck back in 2006 but, when I redone it I adjusted them as close as I could get and they don't look bad. I will go over them again to be sure.

Are there shims that should go behind the latch ? Seems as though mine are right tight against the cab. That could be the problem.. it almost seems as if the doors aren't going in far enough but, when they are closed, they line up nice and flush on the outside.

When I close the doors, I have to shut real hard and apply lots of push to the door handle to get to latch. I also thought it might be a problem with the weather strip on the doors. Could be to big, I don't know, don't have anything to compare them to.
