I already have screwed up the ends, that's why I am looking for a new one. If I can get it to move, I'll grind the ends to get through the holes. I have been hitting it with het, PB Blaster, and the hammer, but it hasn't budged! I got one out of an old yamaha years ago with an air hammer, that one didn't go through the engine cases. I was hoping that someone had discovered a magic bullet that worked better, but haven't found anything on line. Does anyone know where I can find the part numbers for the older bergs to compare? There are a couple on ebay right now.
