If you compare this picture to the one in my original post, the only thing missing in mine is the special tool to install the hub to the lower crank. The instructions tell you what size tool this is and it can most likely be purchased at any home improvement store. If not then I know Metco sells it separately. The bolts that connect the ring to the hub aren't socket style and this only matters if you go with an underdrive(6.55") ring. I lost one of the aluminum spacers but replaced it with a chrome one of the same size. I had another complete kit to compare it to. Lastly I need to pick up some M10 lock washers for the three hub to crank bolts on my way to ship this to its new owner. I hope this answers all questions and thank you for your interest.
