I’ve been trying for remove the car seats of an ‘89 911 cabriolet and encountered these stubborn 6-mm Allen bolts that secure the car seats. Some of the bolts were stripped (not by me) and the good ones are very very tight. So I attempted to use a chisel to loosen those already stripped bolts but had no luck getting any to loosen.
The bolts felt like they were welded to the plate/s and would probably stripped them if I forced the issue. Any suggestions or recommendation to get these “bolts” loose? BTW, the driver side car seat is power assisted and has 3 bolts per rail (total of 6). Thanks.
