Nice 'tool', great write up McGiver! On my 560SL, someone had been there ahead of me. I was all set for lots of fun, having read all about this bolt here, and the caveat about not using the lock pin. Mine came right out with a regular length ratchet, first tug! Now, why would you want to over-torque it back in? I can't imagine the thing 'spinning' out against the airbag far enough to pop the wheel out of those splines, and I'm sure this isn't the last time the cluster is coming out.
