Silverado body mount repair

So i was in the process of installing step bars on my 99 silverado. The front passenger bolt i could not get out but i finally got it out today and when i looked at it there were no more threads on it. im guessing the threads are still in the hole? i believe i now have to cut on the part in the floor where the bolt threads in? im in need of some assistance, thanks guys!

try a tap first, it could save you a lot of time and money
If tapping isnt successful the next best thing would be to make a scab plate to weld over the hole, drill the center and tack weld another nut on the top of the plate before welding it over the bolt hole.
Basically making a new body mount.
Try a thread chaser to clean out any old rusted parts of the bolt. If it is stripped out completely than do as tbplus10 (Tim) said.
