the one thing you never see, except on the original ram air option cars is the knob under the dash for the flapper to open the scoops. It is very rare on the 69's, not sure on the 8's or 7's.
The resto shops don't sell em. A while back there was a guy who had a couple for sale that were reproduced from the original I assume, and wanted 1K a piece just for the flapper. A bit steep for the average joe.

But, that to me, is what makes the ram air unique. The ability to open or close the scoops.
