Started drilling the holes for my crossmember and decided to work on something else (I hate drilling holes).
Decided to cut my tunnel up to use it to create the new tunnel.
Ended up moving it back and triming the front part back then made a filler plate in the center. Looks like I am only adding about an inch or so in height and most of it in the center.
Tried to make a filler piece that matches the original floor.
Where I left it for now
