    braze it up...tryin to weld it is almost a lost cause because the metal is so thin....unless you are really good with a mig i wouldent even try that route..

    well what i did...i dont know if its the correct way or the best way but it worked well for me...took a wire coat hanger and used that as brazeing rod...took a torch and sealed up all the cracks...all the cracks i fixed are still holding up fine but a few new ones showed up...i need to pull up the carpet and do it again...i dident use another sheet of steel either under it...but i am sure it wouldent hurt anything if ya did

    If you can sandwich the area with some thick sheet metal it would be the best.
    When I was doing a frame of on my 73, the whole section was rusted out so instead of getting a replacement, I got a 0.120 plate and formed it with a couple of bends to make it stronger and welded the nuts from under from the original floor.
    Now I have a great thick bullet ptoof floor.
