how the F do ya get stripped seatbelt bolts out?

[jon_volk]

well im trying to get my f-ing seat belts out and the previous owner attempted obviously and stripped out two of the torx bit heads so i cant get a bit to bite into it. the bit just twists out and it looks like the actual bit is starting to twist b/c of this. i cant get a good grip on it w/ vise grips either. any suggestions? im really gettin pissed.

thanks.
