the extensions attach via 2 bolts. You slide them into the swingarm where the axle used to go, then there is a plate that goes on the inside of the swingarm on each side and you bolt into the backside of the extension through the plate to secure them. 4 bolts and you can buy them at an Ace Hardware store. The brake line looks like youre going to have to crimp the banjo fittings yourself though. In the picture, they are boxed separately from the stainless line. The other thing is that you will need to grind or cut down your stock brake block on the inside of the swingarm to install these or the tire is going to rub on it and probably eventually pop.
