Thanks for the reply's, they are cracked at the bottom, baker lights, i think, and one crumbled in my fingers, so i deff need new ones, they were also leaking out the o rings too tho.
I have now contacted everyone, only Repco gave me a reasonable price of $130 for 525cc each, but i would need to do stuff to the ecu im sure. I really really dont want to do that at all.
My intentions were to leave the car completely stock forever, as that's what makes it such a unique example, as its only done original 80,000km.
Repco said that they could 'try' and repair them for $278, But I doubt they would be successful, due to the age, and just deterioration
Thanks for all the advice! cheers,
