There are _no_ parts available separately for wastegates, period.

It's not regarded as a dealer-serviceable item.  The only part numbers
are for the whole assembly.

Audi always uses a nut with a thin washer underneath it.  I've noticed
that Superchips _always_ replace these with shouldered nuts if they
shim a wastegate.  Shouldered nuts (and especially missing part number
tags) are a sure sign of fiddling about.
