I removed the third row seat from my TB EXT and it left me with three stud bolts sticking up across the floor. I would like to remove these without cutting them, if possible, so I can reinstall them and the seat if needed. Looking underneath the TB, I do not see any obvious welds holding the studs in place. I am wondering if I can use a block on top of a flushed nut (to protect the threads) and a hammer to knock these out, flip them and then retighten the nuts from underneath so the holes are filled. Or are they indeed welded into place somehow?
