I noticed my seat belt wasn't working the other day, i'm still alive, so i started to take the bastard out. The shoulder bolt and bolt where the belt reels up came out with no problem. However the bolt on the floor didn't move even with a 3 foot pipe on the ratchet. Needless to say i soaked it about 2 weeks before with wd and it still stripped out on me. What do I do now???
If worse comes to worse I think you can take out the whole plate, which is welded to the body. Lots of work and should probably be done by a professional welder (unless you're good enough to do it yourself).
Other option is to try and hammer in a bigger torx bit to get the shape back, but those bolts are pretty strong.
Problem is that the threads on those bolts are relatively fine. If you've got the bolt up at least a little bit you can get a vise-grip pliers in there to turn the bolt head. You'll probably need new bolts when you're finished.
