Hella bellows: A004538 availability

[goldsax]

i have called our friends at A8 parts and else where re. the bellows that aid in changing the manifold length. no joy
Audi want mega bucks for it.
i only noticed while doing an oil change that the link between the bellow and link arm had fractured and could not be joined again.
i thought i would ask members if they know where to get a reasonably priced one before i am committed to being fleeced
cheers raj
