It might require a hook, but you can sign up for Share This and snag the vertical code you're looking for. If I'm not mistaken I was using a simple hooks plugin that allowed me to insert the Share This code before and after the head. Can't remember for sure but that might get ya in the right direction. You just have to play around with the before and after deal. To give you my honest opinion though, I feel as if the horizontal looking plugins work better. Add this screwed with my URL names and Share This slowed my site down. Then again, I'm not social con expert.
