Ahhh..... the joys of adjusting doors with little/no adjustment.  The latch mechanism on my drivers door was badly warn and I scored a better one at show that solved most of the issues for latching.

With correct style of weatherstrip installed, my E doors look like the are open even when latched completely and require a little bit of a "slam".

Wish I had some better advice.

Thanks for your response, been away from the DE for few days and just gave the door a little shove and it latched perfectly. Maybe it will continue to be this way

I have trouble with my EF too. I have to flip the catch mechanism on the door to one certain spot in order for it to stay closed. I finally had to start locking the door at shows because the window got broke from people trying to slam the door to shut it. Which makes me think of a question I have.

For safety sake, I replaced the latches with mini bear claw latches. The work great you can lean against the door while turning a corner and the door will not open. I consider my truck a survivor and maybe not a concours restoration.
