70 Charger console carpet question

OK I bought the console carpet kit from Dante's. It came with three pieces. Two glue to the sides, pretty easy to figure out, but what the heck is the third piece? What's with the vinyl sewen on the ends of it. Where the heck does it go? It's an auto console if that matters.

Any body have pictures or instructions?

The third piece goes around the rear of the console, below the chrome potmetal piece there should be a sheet metal piece.
The carpet covers the sheet metal piece.
