My rear doors both leak onto the rear seat. Is there a fix besides replacing the seals on the cab?

Are you sure its the seals? The reason I ask is I have seen the 3rd brake light leak into the cab. If its the seals, look at lmc truck

It looks like the front door seals have shrunk. The from seal over-laps the rear door seal. I slid the from seal back about 3". Don't think the front door seal being short in front will be a problem.

No moisture in the headliner or pillar. Don't think it's the 3rd brake light.
