Yes you can, as a great way to get to the 17mm nuts from below, use a deep well socket and then use a 'wobble' extension on it. It works PERFECT!!!!!!! I used an extension bar about 10" long that came in a set of 'wobble' extensions from Craftsman (Sears). It was definitely worth the $30 for the set, for all you need is just a little angle. I changed the risers by myself in about an hour rather than the three hours that most people spend on fighting the nuts on the bottom. You can use a standard socket but the deep-well gave my hand just a little more leverage to push it over the nut.
