Installed Currie rear track bar, what do I need to measure from to make sure it's centered?

 

Is it adjustable and do you have a lift kit installed?

I think I have seen like 100 threads started by "Hellbound" all of them having to do with changing out suspension parts. I didn't mean to make this sound rude, just trying to figure out the situation

But I measure from the middle of my tires to the middle of the frame on each side.

As a starting point, when I put on my suspension, I used my sway bars as the starting point to know how centered the rear axle was...

 

No lift, I have been replacing all the worn stock parts from when I had DW with better aftermarket parts.

I have the Currie in the front and wanted the same in the rear.

Its a nice track bar that has a poly bushing on one end and a Johnny joint on the other.

When I removed the stock bar I measured from bolt sleeve to bolt sleeve as best I could then matched the Currie to that.

Now I just want to make sure its centered on the Jeep and need to know best place to measure from.
