Bolt holes lined up perfectly with the C4's mounting points, so installation took maybe ten minutes. The center support holds the lead screw steady with zero wobble during threading. Exactly what I needed to replace the worn original.

Machined true to spec, so the lead screw slides in without any wobble or binding. It locked down tight on the C4's saddle and the whole assembly feels more rigid now when I'm threading. Exactly what the parts list said it would be.

The mounting hole alignment was spot-on for my lathe's tailstock end, so the lead screw sits dead straight now. Swapping out the old worn part took maybe ten minutes, and the machining finish on this replacement looks factory-clean. Quiet running, exactly what I needed.
