metal floor to wood costs ?

[RShaips]

I am thinking about coverting my 67 SWB floor from steel to wood. I am almost done restoring the truck except for the bed. The floor is decent but still needs work. Has anyone made their own wood pieces rather than buying them ? Is there a pattern available ? I know I can buy all the strips and hardware for a resonable price, but the wood is very high. I have access to equipment for making my own wood pieces. Thanks for the help
