I did use it a lot back then. Used to do my own work. Water pumps, timing chain (when they were still chains), brakes, a CV joint (once), even pulled a tranny once. But...that was before cars became the ridiculously complicated beasts they are today! Now I'm at a loss...I think just about everybody that has tools has one sitting around somewhere that's never used Oh and you want a 6 point socket the 12 point ones can break real easy
