Good advice from all. The 123 steering box, as far as adjustment does not act like an American box. American boxes are very easy and predictable to adjust. Plus on an American box you turn clockwise to tighten.

Yes, there's good advice and warning here about getting it too tight. Not only can you get it so tight that it won't return after a corner, but you can get it a little tight in which case you have to tug ever so slightly to keep the car centered in the lane while going down a straight road. On a long haul it will wear you out, mentally, not physically.

Also these boxes do some wierd things. If you just starting torquing on that allen bolt, it moves something in there that's a tight fit. Don't torque the Allen screw hard.

Good luck,
