I am a long way from being to the stage of doing this but was wondering if anyone had plans/dimmensions on how to make the wood floor for my truck which is a '50 3100 shortbed? I have the lumber and the tools but don't have the dimensions, and/or steps for drilling the mounting holes, including the offsenter washers so I thought I would check with the experts! Many thanks in advance. Also curious what kind of routing detail I need on the edges for the metal strips to sit into.
