If you spend $800, you could buy a new welder, buy floor pan replacements, and do it yourself and come out with a new welder and the job done. Just my thoughts, because it's not hard work, it's just time consuming and tedious. If your frame is ok, the pans don't have to be perfectly installed as long as there solid, it would be a great job to learn from. I did it on a 54 chevy and had no clue when I started what we were doing, and still don't for that matter.... but it came out fine..lol.
