Don't have to argue because there's nothing to argue about. :finger:
The torsion bars have absolutely no effect on the front end alignment. The indexing of the torsion bars has nothing to do with the alignment either and I doubt your local LEs Scwab or such will even touch that. THat's simply an issue of installing the bars correctly. If you go into an alignment shop and ask for an alignment they will not even touch the torsion bars 9wouldn't even think to) That's not their job because they aren't part of the alignment equation. You will have to fix the indexing yourself or have a regular mechanic do it. The alignment adjsutments are built into your tie rods and A-Arms, NOT the torsion bars.
On the other hand, if you install the new torsion bars and change the ride height, then you definately would want to consider an alignment, since changing the angle of the suspension arms will affect the angle of the wheels.
Changing the torsion bars themselves has no more effect on alignment than changing out a shock or putting taller tires on. Which means, no effect at all.
Just reread XSAL's post. He did install A-Arms, and so should have an aligment. I didn't catch that when i read it before. Doesn't change the argument any though!
