Watto gives you a lead on the location of one of the parts you need (Watto broke up the droid and sold it for scrap, predictably). Locate Pegin Dulin (-2977 1911) and speak with him. He'll send you to The Jawa Fortress (-6152 1811) POI. Speak with the droid C4-ZX (-6152 1811), who will send you to a local miners camp, which is besieged by Sandpeople (CL18). Speak with the injured Miner, and your Quest will update. Find and click on the droid Chassis in the tent nearby to finish the quest, and then return to Watto.
