Audi spares pricing policy. Almost everthing can be got from the original
manufacturers (ATE, Lemforder, Bosch).

Yes, but it's even more expensive.

1988 - the TORSEN model with the MB engine. The ur-quattro in this form
was never imported to the USA, but the spares fiche identifies all the
components you would need. The later system is more complex, though -
instead of a single pump it has a double (tandem) pump feeding brakes and
steering separately from a common return.
