Since you're a tall guy and you're doing your own install, and you're taking the seats out anyway, you may want to check out the threads regarding tunnel removal and seating options.
If you're comfortable with the sliders installed, great! I wish I could have kept mine, but at 6'6" I needed to get my seat as far down and back as possible. If you ever decide you need more room, you're welcome to EM or PM me for details.
Removing the tunnel the first time is a miserable job but definitely easier without the transmission in the way. Once it's been out and cleaned, it's MUCH less of a chore and facilitates making other upgrades, such as better driveshaft loops and stronger U-joints.
Ohhhh...you thought you were done once you got the motor in, huh? Nope: that's just the beginning!
You'll see...
