I sometimes joke about how expensive some of these parts can get. The plastic molding that covers the top flange of the rear deck just behind the seats is called "luggage stop molding". Most cars have a scratched, warped remnant - like mine - and I went shopping for one a few months ago. Mind you, they sell on Ebay for $10 all day long, but they are scratched, dented and warped. I finally found a new one for $70 - through Chloe - and the joke goes on from there.
This is an add from a 1970 Road and Track with the full line of Amco parts for the S30. It includes the bumper bars, foot rest, and the luggage bar. Shift knobs were available in lether as well as walnut.
