Trunk floor extensions / dropoffs arrived today, with these doodads - one for each side. AMD describes it as a "tail panel brace which goes from the tail panel to the trunk floor extension." Never seen or heard of it. Anyone got any pics of one of these installed? Google image no help - it confuses it with the trunk latch support. Camaro Assembly Manual doesn't have anything about them. Is the Fisher manual that covers all GM worth getting? Is there a Chevy or Camaro-only Fisher manual? Not seeing any.
