Ok, i was working on my E-brake on my 95 SE, and to get at the cables i had to lower my exhaust. Being as it is a 95 the bolts were seized to all hell. I tried anti-sieze and WD-40, nothing worked. So i got frustrated and cut them off with and angle grinder. Now i need to rethread the bolts on, but i cant get the bolts out of the Y-pipe. Again ive tried WD-40 and Antisieze, ive banged on it like mad with a hammer, ive treid using a socket set, a wrench, anything. Nothing will get them off. what can i do???
