A tool set for implanting bone screws in a human spine, followed by the implantation of a longitudinal connecting member into the bone screws includes a pair of independently mountable and manipulatable elongate guide tools that form a unitary tool guide when desired. Each guide tool includes attachment structure for independent operable connection of the guide tool to an arm of the bone screw. The bone screw/guide tool attachment includes an undercut and/or recess so as to resist separation of the guide tool member from an attached bone screw. Further tools include a removable stabilizer, a cooperating bone screw driver with an attached stabilizer, a closure starter/reduction tool, a closure driver and a counter torque tool.
