Joeker,

However, my little opinion:
it looks dangerous since almost the enture force is loaded on the bolts. And I am afraid that they are too long and too thin to sustain the torsion force in long term usage. You might need to transfer some of the force via the cylinder. The way to do so is connect the cylinder to the steering via 6 short bolts, then to the bosskit using another 6 short bolts.
Some welding and drilling job will be required. :)
