Now that I'm back from the coast it's time to get back into the garage. Almost ready for some black paint. I'm hoping to get the bed back together this weekend. All the wood is cut to the proper width which is 6 3/8 at the corners, 7 7/16 starting at the wheel wells, and the two in the middle are 5 7/16.
Here's the link to GMC Paul's site for the wood info:
