We've already had a thread about repairing those studs. Take a look here for some other ideas.

 

There's also an article in the Articles section with at least one method of doing it. I'm not saying there might not be others, but wanted to point out that there are some existing materias on the subject already...

 

Thanks guys!

I realize there was a thread on this, however, I was looking for a method that was not as involved as the other methods (JB Weld, rustproofing, welding, etc), yet providing a very reliable and permanent fix.

 

Keep in mind that, with those rivet nuts/studs, you will need to drill holes up into the floor, risking drilling into anything on the other side (like wires, hoses or carpets). Also, you will still need to deal with waterproofing -- put some silicone or something on the rivets before installing them. And, you will have to deal with the bump sticking up on the top side of the floor, although it should be small enough to not be noticeable through the floor padding.

You might also want to consider pulling up the carpeting so you can put a reinforcement washer on the inside of the rivets before setting them -- the floor sheet metal might not be thick enough to hold the rivets securely.

Finally, you will need a special tool for installing those rivets. They're too big to use a normal hand pop-rivet gun.

If you do decide to use the rivets, please let us know how it works out (pics, too, please).

 

I'm a big fan of rivnuts, and those rivstuds look very useful for lots of applications. Bill C did a great job with the chemical repair method, but it is nice to have options.
