...if it is like my 37, and it sounds like it is, there is a rubber strip that attaches to the lower section of the cab and goes against the door when it shuts and seals it.

...just as info. My door panels were so beat up I covered them with some thin foam and fabric. When I closed the door the rubber strip let a "mark" on the fabric and it also caused the door to bulge just a little. I knew my doors did not, and have not, shut the best since I did the truck. So, I ended up taking a razor blade and just cutting/trimming the cotton picking rubber seal off. The doors shut better then!

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
