Sireland, tunnel mods on hold until I install the motor, tranny, and Alterktion and everything is in place. Then I'll take the removed floor section, split it into two halves on the trans centerline and tack them back in place on the sides. Then I will try to "close the book", working the halves back to their original position cutting as I go to get to the minimum interference area, and weld the seams back up. Then I'll fashion some sort of new cover piece with box bends. This Tremec kit uses an inline shifter so the location isn't stock and you don't need the tunnel hump.
