If it an 1 1/8 thread I am going to assume that theres a bung in the end of the square tubing. Why not just cut behind the weld, remove the bung, shorten it the amount that you need, and weld the bung back in? Figure out how much you need to shorten it and leave some thread sticking out so you still have some adjustabilty.
