    Hey Grimster, hows it going with that girlie? Good I hope.
    Hey listen, you've just completed a floor pan swap on your rig didn't you? How bad was it? The reason Im asking, is that I know that you can stop rust you have to cut it out to keep it from spreading. But my floor is looking pretty good. The problemo is that the floor pan under the aft bolts for the front seats has cracked I guess from well.... Some weight, and this was not repaired and now has since started rusting. I have preped the metal with Rust-Mort, and its now black.
    Im thinking about fabbing some lapper plates to weld over the infected area and undercoating top and bottom. What guage steal would you recommend?? For this weight carrying location? 20 guage or better? Or should I really just cut the hole deal. How much of pain in the ass was it REALLY?

    Thanks, bro

    I just fixed those cracks on my truck they were really bad. We tried using a welder, but it was burning through the floor. We ended up bronzing them closed. They seem to be holding up really well, but its only been a little more than a week. Good luck.

    You know the older trucks don't do that. I don't know if GM strted using thinner metal as the truck got newer. Keith found the same issue with that 86 he's parting out. I would use 18-20 gage and maybe some big flat/fender washers to spread the load some.

    Yeah, I talked to my dad and he said my uncle has his welder at his house here in Nashville. And I now have the 20 guage and some other misc. strips of metal and some BF washers. So Im gonna get to doctoring this week.
