Stick a misalignment spacer on the head end of those bolts before you fit them, prevents the ring of the rosejoint being able to escape.

IMO theyre fine, as long as you dont try to space them too far away from the steering arm. If bolted to the arm, the bolt is in shear (well actually tension if its direct contact and the ball is clamped to the arm) whereas when you get a good distance away youre putting the bolt and any spacers under increasing bending loads. Before anyone jumps in, high tensile bolts WONT save you from bending loads.
