We used OBX (ebay) adj trailing arms on the wagon we lifted. I've heard forester arms work too which I'm sure is the cheaper way to go, but you still get a taco arm. I've never been a promoter of ebay parts, but I couldn't see anything wrong with the OBX units. Just as heavy as oem, but tubular and you get a bearing instead of a bushing up front. I'm curious to hear long term feedback from the owner of the wagon. He did say it took the shop a long time to align it, which you should expect if you go the adjustable route.
