DIY Swaybar Concept?

[LetItSnow]

Stop me if you've heard this one before...

After some searching, I haven't seen anything along the lines of this solution for our dismal availability of suspension goods. I've seen a couple of pictures of the rear swaybar (anti-swaybar, call it what you will) on the SVX, and I just want somebody to verify that this thing is dead straight between the bushings.

If it is, then what's to stop us from ordering one of the bars in kit form from a performance shop for a reasonable price ($190-260, I've seen)? By just specifying length, diameter, and arm length, this shouldn't be unrealistic, yes?

I'd appreciate any input before I throw heaps more effort into this task.
