I have started to replace the carpets in my 81 C3. I'm counting on finding and fixing lots of stuff along the way. My current problem is in trying to remove the seat belt anchor bolts. So far I have managed only to explode a T-50 Torx bit. The anchor bolt did not budge. Any suggestions on how I might coax theses bolts out? Or would I be better off to cut and trim around them? Any other hints or kinks regarding carpet replacement would be welcome as well. Thanks bunches
