I am currently hacking into my floor to fit the T56 in behind the LS2 and want to see what you all have in the way of modifications to the tunnel. I am wanting to retain as much of the original floor as possible.
T56 is supposed to be level. By the time I finished taking off the top of the tunnel it was back to the front of the rear seat in my 64 but I also had a mini tub and 9 inch rearend. I can only show from the bottom.
