Makke sure that you're adjusting the right thing. You may just have the upper hinge too far out, or the lower too far in, or both, so that the door tilts a little out at the top. Try loosening it and pushing in a little. A little compensation goes a long way here, but youmay have to make several attempts to get it right. Watch out for interference between the front edge of the door and the fender. Also, if the hinges have a lot of wear, you might find it helps to remove the shim from the top hinge, and add it to the bottom one. That's especially true on two-doors.
It's also quite possible that the doors have changed their shape a little over the years. Get the panels lined up perfectly, and get the height right, and if the top is still not seating well over the weatherstrip, you can bend it in a little, just with muscle power. Open the door a little, open the window, sit on the seat, brace a knee against the inner panel, and yank inward on the top. You can also lever it with a two-by-four, but don't do too much. Check frequently so you don't overdo, and try to avoid twisting.
