I was going to replace the crumbled foam flaps in my heater box when I
had it out earlier this year. Got all the parts on hand, but when I
looked at the setup, it seemed to me that the ducts close pretty much
well enough without new, or any, foam, so I skipped that step. It's
winter now and there isn't significant enough leakage to matter. I don't
think I made a mistake.
