It would allow you to move it forward a touch since you would use a non-bent trackbar. You'll want to do this to clear the diff. Just watch the pitman arm clearance. The RE mount may work, but I haven't used it. I built one similar for my wife's XJ for the RE bar.
Here's my TJ though at full bump. Yours won't need to be so tight, this has 2 inches of stretch.

If you have the track bar enter the bracket at an angle (say 3 degrees) that is slack for track bar movement that you don't have otherwise. I can say that changing the track bar 3 degrees was one thing that eliminated my DW.
what slack? unless you are using a bushing, and having it enter the bracket at an angle... but that would be silly...
