New trunk seal, now I can't close the trunk

Yea it makes sense. There is no V lip on this seal, the seal on my Barracuda has the V lip but if you look at the end of this seal it is in the shape of a D. I have clamped it down with thin pieces of wood and let it set for over a week and it just pops right back up, I also used a hair drier and wired the trunk down as far as I could get it but once I lifted the trunk lid back up up popped the seal. Like I said this seal is real soft, I just think it's to tall. I am going to try and drill some vent holes in it before I replace it so the air can escape when I shut it, I have seen some seal like this on some newer model cars it's worth a try. At least the company that I purchased it from is going to send me the V shaped one just incase it does not work.
