Stone7, I think Andrew gave you a very reasonable answer that could be right. With that attitude you probably won't last very long on HEF. We try hard to keep this a forum for civil exchange of ideas, not just bashing people who try to help you. If you keep this up, you won't get much more help.
I agree. I've worked on JLG machines for years, and although I can't recall every fastener and stud on every machine, I really don't recall seeing something like that on one, I think Andrew gave you an honest guess at your mystery part.
As for your response to "stuff it", that's unacceptable behavior and will not be tolerated further. I strongly suggest you realize you're having conversations with folks the world over. You can not possibly get a good read on someones inner thoughts or intentions by reading innocuous words written by someone, certainly not good enough to tell them to "stuff it champ".
As for this kerfuffle, it better come to an end, and I mean now.
