avery, you may want to box your frame wherever you tie your cage into it or its going to crack....i actually have cracked a k5 frame...it was a trazer and the drives side started a crack thru a t-cace crossmember bolt and started up the side, it wasn't opened up, so i pulled that bolt and v'd the crack and welded it, & a small 3/16 fishplate no more problem, i had the truck for 5-6 yrs longer, no problems, so a cracked frame, isn't worth the space that its taken up in avery's thread! no more talk of it!
i'm glad you decided to not chop that bed up, i wish those rust free environment came a little futher east, a perfect bed here could fetch $750-800 easily...b4 gas goes back up sky high...is that rust free full vert w/out windows still sitting around for $1500?
