:stupid Drill the heads, lift the bracket off then wind the bolts out with vise-grips!BikePilot said:If I remember right, on a 97 TLS the bolts are totally recessed into the damper mount bracket and no real chance for getting vice grips on them (hope I'm wrong).
If nothing else, dril the heads of the bolts off, take the damper mount and lift the tank, then use vice grips. You could also try drilling a smaller hole down the middle of the bolt and using a screw extractor/easy-out type thing.
BTW the quality of allen wrenches used makes a huge difference on how easily stuff stripps. I have found that impact rated allen sockets (even HF ones) rock and of course the snap-on ones are quite good too
