1994 suburban hinge gaskets-where to buy new ones?

[IADC43]

The barn doors on my suburban are letting the carpet get wet when it rains. I did the foam tube inside the weatherstripping trick. I'm sure the hinge pins are tight. I don't like the gap of the top of the doors, but other than tweaking them by bending them by hand, haven't seen where else to adjust them.
I put a hose on the roof and watched for water, I can see water come in and I am rather positive that it isn't coming from above the upper hinge.
The lower hinge gaskets look to be toast, I'm thinking that is where most of the water comes in.

It looks like the surround gasket has shrunk or whatever and won't fit the corners properly either. I cut it at the bottom and pushed it up to the top corners and to the lower corners. There is now a 2.5"-3" gap that it was lacking to seal.
I'll still want the hinge gaskets, now probably the surround one too, if I can find them to be reasonable.

Sorry I can't help but I was wondering what this trick is and do you have the link?
