[Mark IV]

I'm a dealer......so if I tell you to tighten them till they strip and then back 'em off half a turn, you will do it?

Sadly, the "feel" method is probably the best unless you are using a calibrated impact that you can set for maximum torque. One of those things you just gotta "do" until you get the feel.

Oh, and if you don't safety wire your KO's, you be askin' fer it.......................
