Outer Limits 4x4 Board

I think i have snapped a valve spring in my 4.2 GQ. Does anyone know where i can get heavy duty valve springs? or perhaps ( dont know if i am explaining this right) helper springs, the springs that sit inside the valve springs?

I am located in queensland so somewhere local would be good but not essential.

Cheers,
Welchy

Crow cams australia has some Heavy Duty Double Valve Springs for the TB42, not sure if they'll fit the TD42 though
