Wayne - I snapped a pic of that, too, at Petty's Museum a few years ago.

Here’s the 3/8 scale Plymouth in the wind tunnel. Notice the original colors of the body and windshield.

Look how much of the inner trunk lid was removed.

An actual Road Runner!
Check out the hood!
Turns out that the Satellite hood had less drag, so Petty ran that. See the rubber front bumper? Cool!
Note the full width front spoiler.
A rule change to “as wide as the frame rails” took effect for 1971 so this was the only time this spoiler was seen on a Petty car.
It would be cool if one of the Petty Plymouth clone cars ran that spoiler, rubber bumper and a real Road Runner hood.
