Finished up my buddy's engine refresh, survived Christmas travel and illness, and now back on the truck. I was able to chop down the bed over the last couple of weekends. 8" behind the tire and 12" in front of the tire. I kept the stake pockets and placed my cuts on the top rail to get rid of the most severe damage. I had more warp/shrink on this truck than I did on my Chevy, so I had to do some dolly work and use a little filler. I hope it all disappears when I get some color-matched paint.
Now I can pull the bed off again and start laying out the cuts on the frame and borrow some more jack stands...
