I hope you don't take this the wrong way but perhaps you can't see it because you lack experience. Based on what I've been reading, you don't even seem too interested in obtaining it. I help pit for Mel on a regular basis and I can assure you that we're NOT changing out track bars "regularly".
So in 3 yrs I have bent 2 Trac bars. Am I inexperienced? Not a professional by no means. I have been wheeling for about 15 yrs. So I do have experiance. I have bent in by being twisted crawling and prerunning it. So both worlds. It isn't that I am not interested in obtaining help or ideas.
