My 65 steering box mounts cracked on me. Cant remember if it were at the top plate or base at K, scary speed wobbles at about 10 mph. Had to limp it home 9 miles in the gutter at ~7mph. I'd go over all of them and gussett where you can.
Maybe some had better welds than others or some years had more metal? The metal the is in the steering box mount on my K frame is far thicker than the other mounts and the welds are perfect. Way better than the rest of the K frame which was pretty piss poor in general. It's as if two entirely different factories welded these two areas. Oh well. I'm goons let the original steering mount stay as is and gusset the holes for the control arms.
