Just cleaning up the firewall on my 68 Polara. I'm curious what if anything the oval cut out, albeit it plugged, behind the drivers side head is for? Or does it have any purpose? Seems to be a haven for rust. Here's a pic

There should be a cover to prevent fumes and such from getting into the cowl, as that is the fresh air plenum that feeds the hvac/floor vents. You don’t want the interior to smell like the engine bay!

The cowl drain on the fh side should have a thin rubber flap that covers it from "fumes" yet will move away for water to escape. Not a solid seal, just a deflector of air as they usually curl a bit on the corners with age.

It's there to prevent rust.

Made from the correct thickness EPDM rubber. Not thick and stiff like others. It doesn't have Mopar part numbers molded on it but those aren't seen when installed. What is seen is a perfect shape, CORRECT thickness (approx. 030") flap that will perform as well or better than the original factory...

Don't believe that's the right one for a '68. Think it's the same one as used on early B-body- 2167001, fits 65-68 C's..

It was the Eastwood stuff. Actually a buddy of mine painted the air cleaner years back, a seldom-seen member here- @red skunk
