WTB: 28.9mm or larger Torsion bars

Hi, I'm looking for big bars. I'm looking for 28.9mm or larger torsion bars (but not 33mm ones from performatek..that's TOO big) for my track 75 that sees street use. I'm hoping to find some used bars too offset the shipping and cutoms costs of buying new ones from another country. I'll pay pretty big bucks for these so let me know if you know of any.

And to clarify, I'm looking for torsion bars (torsies) and not sway/anti-roll bars.

I'm also insterested in long 25.4 or 27mm torsion bars for my GTV-6. Cheap is good.

Thanks!
