Try compressing the suspension down to expected ride height, and watch what it does.
If nothing else, it's closer to the frame mount. And that alone will "shorten" the distance the trackbar needs to cover.
You have a long travel suspension it looks like. And no driveshaft yet? Up on frame stands with the suspension relaxed at full droop maybe?
If so, there is ALWAYS something else that is going to be the shortest link and limit wheel travel. If you want a long-travel trackbar and draglink and driveshaft and any other thing, you are going to have to custom make it.
Your draglink is a little longer than the original, so that has a little more travel built in. But only as far as is safe for the type of rod end joints it uses.
To be close, the trackbar also has to be longer than stock (they travel in the same arc after all) and mounted farther apart.
As Yeller said, the ONLY way to mock up your suspension and steering components so that they work together, at least under most conditions, is to set them up for ride height correctness.
What height suspension are you running? Looks like it's set up for a tall one, what with the tie-rod over configuration, with a riser and drop bracket.
Whatever your lift is, compress the suspension (ratchet straps work for this) until the measurement between the top of the axle tube and the bottom of the frame rails is 7-inches plus whatever your lift. Approximately...
So if it's a 4.5" lift, get the distance to approx. 11-12 inches and see if the trackbar will hook up at this point.
