As far as stock lower spring perches you could try Strange Engineering, they use all stock fittings on their S60 and 12 bolt rear ends. If you look at pictures of Moser or Quick Performance rears you can see how they use fabricated lower spring perches. Looking at the Moser stuff it doesn't look that hard to fab some up if you can weld.
