No pix, but the tilt index attaches with two screws. It will be positioned later.
The tilt lock rod is inserted through the hole in the front of the tiebar and the second return spring slipped over the end..
The front wedge is slipped on next.
Now for the 'trickey' step. While pushing in against the REAR wedge, simultaneously push in on the FRONT wedge with the washer and tilt lock nut/handle as you rotate the nut onto the rod. This is less 'trickey' if the handle is removed from the nut, but then you would have to reattach it with the nut 'mounted'. I did not take the nut/handle apart.
Again no pix, but raise the mounting tubes to the zero index position against the zero stop, and tighten the tilt lock. Align the index to the zero scale on the trunion. Release the lock and verify the indicator does not drag against the trunion.
As a preview, this is how I tighten/loosen the mounting screws. The allen wrench is 5/16" and the box end wrench the same.
