One of the reasons why TTB kits are time-consuming to install is because a number of the stock suspension components that must be removed are both bolted and riveted in place. Each rivet must be removed individually by drilling the head of the rivet off and then driving the body of the rivet out with a punch. There are scores of rivets in a TTB suspension. Here, you can see the new passenger-side I-beam pivot bracket being installed after the factory I-beam bracket was removed. The new bracket mounts to the crossmember using a combination of new and existing holes.
