I'm sure the rules say a blanket is required for the tranny... Either way, I'd still have some kind or plate under my seat, lol.

I'd be throwing a cushion on piece of 1" plate!!!!
That thing's looking awesome, I can't wait to see it run.
I actually picked up an old 94 reg cab 2wd pretty cheap the other day, thinking I might do a bit of pulling with it...if I can figure out how to get it setup right!:evil
I like to be a little different!

Dale it is coming along very fast and looks awesome!
For the guys that think the 2wd units can't hang with the 4x4's, you will be surprised. LOL I had a friend that used to pull his first gen 2wd diesel around here and in Mo. He finally got tired of changing the truck to fit the org's rules. They kept changing the rules because he was beating the gasser big boys and the 4x4 guys. Now he is rebuilding the truck as a 4wd last I heard.
