Best shortbed patch panels?

[HunterRotten]

My dad brought up the wood floor but I really just don't have the truck to do that to. The pictures shown is the only rust on the bed and the guy we bought I from last year said leaves sat behind the fender for a long time and caused the big hole. All of the rust is on the fenders and on the back of the bed. The box underneath is solid but scaley.

I also think the wood floor would make me never use the bed, plans are to get the bed lined while it's being painted.

Being in Ky I doubt I could find a bed in better shape or a floor that has what I need.. I've been to a few junkyards and there simply isn't a floor to cut from.
