I don't know if they're any use for a factory wastegate because I've never taken one apart, but a bunch of the aftermarket 46mm wastegates appear to be copies of Tials - and some of those vendors are selling diaphrams for them:

Do these look even vaguely correct?

I'd imagine you could fab something up for the valve and guide, and springs are readily available (and interchangable, I'm given to understand).

I'm presuming that gaskets can be made, and any seals etc would be standard sizes.

What else is there that wears out?
