I started going down the path of converting my S40 to use the P2 front struts but ended up deciding it was going to cost a lot of money for no meaningful advantage. As a result, I have the parts pictured below, new and unused, available for $130 + postage to Oz Volvoers. These parts cost about $325 to me, so the discount is real!
Crossed out parts not included.
