Has anyone else had enough of slamming doors on these old trucks? I put new rubber seals in and I have to really slam the **** out of them to get them to latch. I have adjusted them to the max, and they still will barely latch when slammed. Are there some tricks I do not know about? Has anyone tried the new latch kits? I will add a picture of them. This is the last aggravation of my project, and I would really enjoy my truck if I could trust my doors to function correctly. Any ideas, cures, suggestions will be greatly appreciated. Thanks, GM
