Insert the Dual Steering Axle (I always use the trailing axle position for 1S) into the Steering Block. Screw the king pin into the unit until the there is about 1 thread still showing.
Using calipers, measure .404" (for 1/12 scales king pin) from the bottom of the Steering Block to the bottom of the e-clip groove in the King Pin. Because the bottom of the Steering Block is not even, do this measurement at the same location for both assemblies to be consistent from side to side. I do it on the side of the Steering Block under the axle.
For the 1/10th scale king pins that I use on asphalt, the length measurement was something like .576-.580" to the bottom side of the e-clip. Just be consistent side-to-side in what measurement you use.
