Almost finished installing the bed on my '55 1st series truck. Applied 8 coats Minwax polyurethane to all 6 sides of the boards. Really happy with the installation. Mar K has a great product. There are a couple bolts left to install. The two bolts in the support channel next to the shock attachment. May have to make a special tool to get the nuts and lock washers on the bolts and tighten them. Any ideas. Pictures to follow.
