this can't be right '70 camaro

[67blackbird]

Gents,
was doing some work on the car- removed the rear window and that panel between the window and the trunk. It does not seem right.
That panel at the base of the window is sheet metal screwed into the body. So when I reinstall the window and put the trim on, I can see no way to prevent rain from running down the window, under the trim and puddling under this panel, or dripping into the body through the screw holes. Chevy used this panel from '70 to '81, so it can't be that bad, right? Am I missing a gasket ? Do I need to pile up a bunch of silicon? Or ???????
In the pic the panel in question is primer grey- trim clips are black. See the gaps that would let water run down to the trunk weatherstripping?

That is the Dutchman's panel and the drains do run off into the troughs that the rear truck springs are set on...... This water is supposed to run off down the back of the car along the seem between the trunk seal and the rear quarter trough.... That's the theory,,,, now in reality I've seen more of that water in the trunk floors than running down the seem LOL. The real issue is if you don't drain off the water collected at the lower back side of the rear window,,,, you"ll have some pretty serious rust issues before very long.

Thanks,
well at least I am not missing anything. I guess I will get to fixing the trunk rust, and then keep an eye on it.
Still seems like a goofy design, though.

By the way Warpath is incredible!!

GM designed it that way to wash the dirt out of the trunk

Just make sure the trough is clean and the water has a clear path to the side rails. Put a dab of sealer on the screw holes before you finish mount the panel and you'll be fine.
