Hey Darin, what's going on down under? I wasn't aware of the holes until you asked, but they are indeed there.
Something else I didn't notice until I looked closer at my scrap piece is that the seal part actually is a rubber coated foam (I read this elsewhere).
I think it is just the nature of the beast that they are difficult to close for a while (or forever). However, I have read of Bullnosers that did have good luck with them and the seals did relax and form after a while. I think even now only a couple days later, mine are a little better than they were.
All good here thanks Cory - I'm just chasing up some parts from the New Year when we visited the US.
That's good that they have the holes. Maybe as you said, it needs to be left in the sun a bit so they can soften up. Keep in mind that your doors have been adjusted to the old rubbers and may have to be readjusted to the new ones.
