I agree not to take off the anti lock brakes. Check your steel tubing size go to a parts store and purchase some long lengths. If you don't have a double flaring tool. Remove a section and buy sections to length. They make a connector so that you can screw two threaded pieces together to get the proper length. Maybe a long and short piece. Purchase a bending tool as it will crimp and crack if you don't use one. This is an all day job and dirty if you haven't done it before. As you won't be exact on length you may need to put in another bend or a slightly larger one.
Don't use crimp connectors or copper tubing or you might total your truck.
