That whole "cover the 4-speed hump with another hump" thing looks really bizarre when it's finished. Yes, the T56 tunnel is a couple inches higher when you are done (mostly due to the ToddRon crossmember because it's very beefy), in the end if you patched your floor back to auto, then did that, and were pickly like me and didn't want to overlap sheet metal, the only thing missing is doing the crossmember center swap, which in my opinion is one of the easier parts. It took me a lot of time to fit and butt-weld the floor pans more than anything else.

72bluNblue did his own version of the 6-speed floor mods.
