I need help finding some pivot points for my tower. I have talked with the tower manufacturer and he said he can add them for $250, which I though was quite reasonable, but he is a good three hours away from me, but about 6 hours from my tower. I have talked with a local metal shop and they said they could fabricate the part and weld it up no problem, but it would cost more than $250. He advised me to find the part and just bring it to him to weld. Does anyone know where I can find the part in the picture below? Thanks.
