The instructions for installing the black 35" push/pull (KPCS0268) tube into the large alum tube going to the elevator (KPCS0305) are pretty devoid of detail.
The cross tube on the 35" P/P tube obviously needs to be trimmed to fit into the big tube and its internal doubler------but it is not clear if the assembly is designed to allow for motion between the two tubes.
For allowing movement, the cross tube (where the 1/4" bolt goes) should have a slight clearance inside the large alum tube, and should have square cut ends.
If this joining of the two tubes is designed to be ridged, I would look for minimum clearance, and a radius end for the cross tube.
Guidance please...........
Mike, we do radius the ends of the steel cross tube a bit, but we don't tighten it so there is no movement between the two.
