Custom Springs

[Emmanuel <efyssas@unforgettable.com>]

Fellow cone fiends,

I am searching for a company that can custom wind me some springs for
the rear of my Chevy Beretta.  The complicating factor is that the rear
springs on this car are wider on one end than the other (cone shaped as
opposed to cylindrical).  I would like to get some progressive springs
that are max rated at around 350 lbs in. and an inch or so shorter.  Can
anyone point me in the right direction?

Thank you,
Emmanuel
