  We apply the One-Sided Action Theorem from the first paper in this series to
prove that Rieffel's Morita equivalence between the reduced crossed product by
a proper saturated action and the generalized fixed-point algebra is a quotient
of a Morita equivalence between the full crossed product and a "universal"
fixed-point algebra. We give several applications, to Fell bundles over groups,
reduced crossed products as fixed-point algebras, and C*-bundles.
