I made the top of trans tunnel removable in my 48, but the only thing I can get to is shifter. And it's more trouble to pull up the carpet than it is to unbolt it from underneath. You will also pick up some additional rigidity in cab and floor if you weld it in. I'm in the same boat today, everything I thought I could do was missing one piece or another, so I finally gave up for today.............. At least it's supposed to be only 90 tomorrow...............
