Working on a variety of gears, the fabricated tool is handy. The stock Corvette steering wheel measures approximately 18" diameter. The lever hole is equal to the rim of the wheel. Pull the spring scale perpendicular to the arm or a steering wheel spoke. Over-center, a "high point" increases drag and should read a total pull of 7/8- to 1-7/8 pounds. Once correct, hold the adjuster screw and tighten the lash nut to 15-20 ft. lbs. Again, check the full left-to-right range pull.
