Bruce, you've probably already done this, but if not-it's worth knowing. At the mount points of the cab and bed are various height wood blocks. PHOTOGRAPH and/or measure them before he "blasts" the bottom. Any of them that are soft,rotten etc,may disintegrate- and you'll need to replace them. I had to "frame off" mine, and the proper height of those little blocks is really important!! Good Luck with your project, we all loved the first pics! Keep em coming.
