    I'm dealing with a similar problem; my cab mount nuts are stripped. I did a post on this but have yet to get any suggestions. I'm thinking about using a hole saw to cut an access hole from inside the cab directly over the location of the nut and replace with a regular nut...

    About the only choice you have is to cut a hole in the floor. I had to do that in 4 places when I put the body lift on mine.

    Cut a cross shaped hole and you can fold the metal back down and re-weld it shut.

    Only suggestions I know of (for GM car) is to approximate the location inside the cab, then cut 3 sides of a square around it, and fold it back. At least that way you can weld the piece back easier than what you end up with using a holesaw.

    cool thanks y'all /forums/images/graemlins/laugh.gif
    well sounds like the votes going for cutting access spot above there and fixing it that way

    i was wondering about drilling and tapping new threads ?

    but if all it is is a welded nut then hmmm,,,



    thanks

    ok, cool,

    another Q: anyone ever cut into panel from above and drilled it out ? how much room is there to get drill at the welded nut ? enough ? or ? and about how far in from the inside corner do you need to cut access hole ? ill use a holesaw bit if i can find one quick enough when its time to fix for him, ill get another chevy truck to part out for doing this for him when he brings truck over

    thanks
