I purchased a used Ford 3400 tractor, it had new ( made in China) sway bars attached. Both bars are the same length, and seem to contain a left and right bar, judging the bends in the bar. The problem is, when I connect any piece of three point equipment, I can only attach one bar. The other bars hole is off about 1", no way I can connect the second bar. I've tried various three point equipment implements, even an implement that is new. Any ideas on what I am doing wrong or can try, are appreciated!
