Thanks for the comments!
DL - What Michael said :) You'll eventually see bracing attached to the B-Pillars. Then the bed front gets fastened to the braces and body. When it's all done it is as stiff and strong as the uncut body. And that's on top of how stiff these bodies are without the added bracing. When it's all said and done I'll end up with a little truck that is a ton of fun to drive and with a very unique look.
