Built LH and RH Torque Tube assemblies per Sect 23-06 Steps 3 & 4. Drilling in steel is not nearly as much "fun" as drilling aluminum. Next, complete ass'ly with short ends at specific orientation per 23-07 ...tomorrow.
Went ahead with set up to measure within 1/32". This is one of few times Vans engineers provide min - max dimension...between 17 3/4 and 17 25/32 (plus/minus 1/64 !)
