Looking for section under the seat. Any ideas ? Already using truck short bed for replacing the bed section. Dose anyone know if the last bed support is a channel piece or full rectangle? Thats the last piece to check out before I put all back together. Do the bed sidewalls sit on the bed floor? My inner walls have also been rigged up. I am going to cut off and redo. I'll post pics later. Got more rust than I thought but getting through it. Thanks Pat
