Jeep Comanche Rusted Out Floor (Part 1??)

So I got inspired to finally do some work on my Jeep Comanche (MJ) project lately. I pulled out the seat and carpet and got a rusty surprise. I will need to cut out the old rusted out floor pan that is full of holes and weld in a new panel. I've never welded before so let's see how much of this project I can DIY fix. Next up is using a wire wheel on my grinder to remove the rust and find out how much good metal is left of the floor boards.
