Yes they are called sway bars. Your pin is in the slot that is designed to allow for the lift arms to swing, be it limited but designed to give it movement. You should have some fixed slots that will line up if you wiggle them some right or left. If not and you must use the slots then you can use second pin in the slot. One piece of advice, you do want a tiny bit of movement other wise during the operation of the lift arms you might have a spot where they bind.
