I've been talking to johnny over there.
he said the upgraded springs we need will not be available until march.
any TC's bought from them so far have just been re manufactured using the original smaller springs....

Thank you for your email.
We can produce 600SP unit with newer heavy duty springs in March.
The price will be little higher.
Thank you again,
Johnny
http://www.torqueconverter1.comI plan to buy one as soon as they're available with the new springs...
the stock springs just bottom out with anything over 240-300 ft/lbs (depending on how worn they are) then you get your driveline hard linked to your engine, and you can feel every power stroke..... (shudder)
The shock from each power stroke will eventually break things like u-joints.....
the downside to stiffer springs is a less "refined" feel while driving (you hear all the suncoast guys mention it)
