So there are holes in the trunk lid for the piece. Damn Guess i will have to leave that thing on.

you say trunk lid. are you talking about the rear spoiler or the decklid panel?

I believe the title of the thread is deck lid panel. I have the pedestal spoiler.

I believe there are no holes for the deck lid panel (yet you seem to be concerned that there are holes like for the spoiler) thus the confusion.

thank you

Just received a custom decklid panel from American Muscle, made by MMD.
This is for my 2014 Mustang Conv. The instructions from MMD sez to remove the two torx screws inside the trunk, then use pry tools to left up the decklid it's held in place by 12 clips. Removing the clips with softsided interior tools, then install 3M adhesive tape to install the new decklid. You can find instructions on American Muscle website. Rick

RickD2xNE is correct. If you don't like the look of that hideous fake fuel cap panel, you can order from CJponyparts. They have a couple of the replacement types that should make you happy. I hated mine, plus the ugly factory panel had a gap from the panel to the trunk lid. Ford warrantied it, but the new one was almost as bad as the original. But RickD2 is correct about the torx screws and clips.
