It was common for those 3 bolts to loosen and woller out the holes in the early A steering gear and screw up the K members too. Chrysler Corperation provided the majority of funding to develop thread locking chemicals especially for these 3 bolts.
To fix it right you would have to cut out that plate, weld 3 new nuts on it and weld it back on the K member. Check the holes in the steering gear too. If they are egg shaped the gearbox wont stay tightly positioned for very long.
