Thanks Andy and Karl (insert sarcasm here). Karl, I'll try to get that 387 ft/lb with a 6 foot cheater bar. If I take the targa top off, I should be able to get enough torque on it. I'll let you know if I have any trouble.
[Given that no one is really sure what the torque is, and given that these are 17mm bolts, I'm going to guess 30-33 ft/lb. Make sense?].
Thanks for all your help (or unhelp as the case may be).
Douglas
