Needing patch panel work for my 61

[JoeKan]

Well since bringing her home and looking over the truck closer I believe the first thing I need to do is to begin working on the rust. It has rusted out rockers and the floorboard is rusted out as well.
Do you think it would be wise to just patch in the rust holes in the floorboard or should I look to buying a new floorboard to install?
I need a video of how all of this is done because I don't know exactly what I should be doing to cut out the rust and replace it with sheetmetal and weld it in. I "think" I can do it, but I'm one of those that someone has to draw me a picture so I can have complete understanding of it before I do it.
Does anyone know of a video that is out that can show me what to do step by step?
Thanks again for the help,
Joe
