See... i dont "have" the tools if it requires welding. A long time ago back when I was like 10 years old, my dad took street signs and made a new floor in his '86 Ford E350... i dont even think he welded them in.
*Edit* Both sides are pretty bad. The backseat area is completely fine with a couple smidgets of surface rust. I have to fix my weatherstripping in my T-tops before i do anything though. Thanks for the help guys
