A large order for composite leaf springs would be the way to go.
Correct me if I'm wrong but I'm not keen on King springs as they have been described as too hard by many club members, and I'm after a more comfortable ride with some off road ability.

I contacted flex form and this was their response:


Hello Justin,

We can make our composite monoleafs for your Datsun.
Shipping to Australia is not cheap. We have recently been using Federal Express and it has been running in the range of $160 to $185. Base price for the springs is $425 for a pair.
Contact us again if you have other questions.
Thanks for the inquiry.

Mark


If anyone knows of a composite leaf spring maker in Aus, maybe that's the way to go?
