console carpet/side trim

The carpet was glued to the console.

The piece you mentioned for the 4-Speed Console was to clear the shifter that sticks up through the 4-speed hump

On my '74 Duster, I mounted the console flush to the floor, and didn't install a 4-Speed Hump when I converted to a 4-Speed. A much better fit, in my opinion. Less of a gap to fill with the carpet, no massive 4-speed hump sticking out.
