Those pictures want me to take a look at my piggies.
Pull the weather strip back and look at the corners to see if there is a crack starting to form, Scrapdaddy was the first to bring it to my attention.
Admittedly the cracks @gonzopancho posted are far worse than most I’ve seen, I suspect there is more to the story like hard driving at some point or mechanical failure with body mounts, cross members.
