Installed clear plastic (from transparency covers) for the windshield and rear window. I cut it in one piece, then glued in the cardboard headliner to hold the "bridge" of the plastic in place.
Applied colored paper over the center body strip. For the hood scoop sculptures, I glued two cardboard strips to the hood prior to putting the colored paper down, and with a short ruler and a popsicle stick, worked the paper around the strips for a sculptured look.
