401742 will get you everything you need for the new pull rod design. As with the previous pull rods, try and make sure they are the exact same length, it's a little harder since there is no turnbuckle, so just play with the lengths and how far the set screw goes into one side. I'd recommend about .5mm of space between the two ball cups.

401743 are spares.

401738 will give you VTD. A new servo mount is still on the way, removing the need for the center spline (401646). In the mean time you can cut 401646 behind the 3rd most forward hole (just behind servo), which will give you a very similar feel.

401739 is just spares for VTD.

401747 is a bit of a mystery to me, I'll report back when I hear more details.

For what it's worth, 401742 and 401738 are fantastic upgrades.
