29 trunk question

[Aaron D.]

I'm in the process of fitting a deck lid onto a 1929 model A Coupe. The deck lid appears to be original. The deck lid has a crown in it going from drivers to passenger side. Is this normal? The trunk won't open because the deck lid is crowned and the panel in front of it is flat. I don't know if the deck lid is supposed to be flat or the panel in front of it is supposed to be crowned.
Thanks for the help.
