Perusing CL the other day and stumbled across an Econoline straight axle setup complete right down to springs and shackles! Ad showed boxes with parts, so I gave them a call. Turns out to have two new finned drums, new Bendix wheel cylinders, new Bendix brakes, new king pins, and new Moog tierod ends. Bought the whole package for $100, and spent today cleaning and stripping it down. Separated all the springs and painted everything up, then installed the new parts and reassembled.
Should be a good donor for the next gasser project!
