Great question. As was mentioned earlier, maybe a track bar drop?
Possible. But better to consider the lower mount right off the bat, after you find out where your tie-rod is going to sit.
On most, when going TRO the tie-rod hits the lower trackbar bolt before you reach your steering stop. In James' case you can see that his is above the lower bolt (hence my question to him), but on many it lays straight across the bolt.
So you either shorten the bolt and run a super thin nut (been done, but does not see the best course of action) or shorten the bolt as part of a trackbar riser install.
The riser also gives you more options on where to mount the trackbar to best match the angle of the two bars to each other. A trackbar drop bracket can be done to do the same thing, but then you might have to make a custom one, or worry about introducing the extra stresses on the frame around the mount. The actual reason the risers were invented in the first place if I'm not mistaken.
While many of us run drop brackets without any hassles or damage or cracked welds, it's not an argument that the riser is still stronger. And though it might not always be "best" for every application, in my opinion it's the best route here with TRO.
Thanks for using our fully adjustable setup. You should be able to simply order a new centerlink from us without the rod ends and head on down the road.
Install the new (straight!) tie-rod, flip the rod ends over to fit the new tapered holes you're going to make, attach the draglink and it should all work together. Once you've figured out just where the trackbar is going to mount that is.
And regarding re-drilling the knuckles, hopefully James has some info on how he does his. Whether he just tapers them from the top and works with the reduced surface area (creates kind of a stylized hourglass shape if you will) or adds some tapered shims like is getting more and more common.
