I installed one on our 2002 chassis and again on a 2012 axle that I swapped into our coach. The first time, I think I had to tinker a bit but it lined up and worked very well. Second time, right into place.
Thinking about this installation, there are three "adjustments"
1. Where the bar clamps in the center bushings and brackets. You can slide it left and right a little.
2. The Driver side brackets. They can be positioned to an extent.
3. The Passenger side brackets. Can also be positioned to an extent.
You don't want anything to rub, and you also want the two end links (long 1/2" bolts in this case) as close to vertical as everything else allows.
What's actually wrong?
Here's a pic of our passenger side.

The vertical boss with surface rust is where the late model OEM sway bar attaches with end links. They added the boss and left the bushing hole used by earlier models. If I did not already have the 7008 bar I could have used the Hellwig version of the 2008 and later bar.
If you are convinced that somehow the end link bosses on your 7008 are spaced wrong, measure that spacing (might be the length of the bar overall, across the two bosses) and call Hellwig tech support. They should have a spec for what that spacing ought to be. I can't measure the exact BAR, but based on the spacing of our end link bolts, spacing is close to 41-5/8"
Don't despair! You're gonna love it! We did the rear also, and the difference is huge. On the road AND on the campsite.
Let me know how I can help.
