So, Lets start with the bed! The pics are upside down because the bed is upside down. Is the rail piece on the inside of the bed replaceable? The one holding the wood. I see its spot welded. Im pretty sure most bed parts are
available in repops?

As you can see. One mounting bracket is missing.

This is the look im after. I dont like the front that low or wheels sucked in like this. The rear is perfect.

Got the bed torn apart today. Not to hard. Just time consuming.

Those side rails are available and replaceable, but you have to locate all the spot welds and drill out every one. There are over 20 on each side. Then you have to weld or bolt on the new ones.
