I have most of the mechanical issues on this truck straightened out and am beginning to work on the body. I need to replace the rusted out cab corners. To do that I need to move the bed. Sometime in the past, a previous owner placed a metal plate over the entire bed on top of the rotting wood boards and welded it to all 4 sides.

Can I get to all of the bolts from the underside to remove the bed? Or do I have to somehow remove the metal bed floor first? Any tips will be appreciated.

Thanks,
Hugh
