i know all this because i actually did the opposite you want.
i took out my jumpseat and put in a center console, and i found all i the pictures of what i did. so here it is.
there is the console in it, so what you would have
this is what i had to cut out so i could get the console to fit in.. so basically this is the piece you would need to track down, and it would be the whole lower valence.
and finally there is the "hole" on the bottom that you will be left with, hope that clears everything up for you!
and as you can see, it's really ugly when there's nothing there. All the wires hanging down and stuff.. not pretty.
