Welcome!
Got a model number for the plow? That would allow you to search in the Manuals - Implements section for the Exploded diagram & parts list.
Is it a simple 1/2" diameter steel rod with a 90 degree bend at each end?? If so many of us (myself included) make a better version using a straight piece of 1/2" round stock and thread the ends 1/2-20 for a pair of Heim Joints. MUCH smoother feel, no slop.
