package tray

I just received from Paddock a package tray (backorder for like, 3 months!) and i just test fitted it to see what i think.. it seems to not even fit! Theres a sticker on the back that says "66-65 Dodge Dart Package Tray" and another that says "Finest Quality" (even though the damned thing doesn't even fit)

Has anyone else had this problem? Or maybe I'm missing some random step?

Also of course, I ordered one with speaker holes drilled and i have no speaker holes. Anyone have measurements or suggestions for that (that is if i don't end up sending it back)?

thanks.
