At one point in the movie Ben, Stephanie's Fiancee, walks into the garage where Stephanie's Dad, Robert is working on a vintage car. Ben identifies it as a 1955 Ford Thunderbird, which impresses Robert, and asks if it is running. Robert says no, says it needs an idler arm. Ben looks at the engine naming off several parts, again impressing Robert, telling him his dad is a mechanic. Later on Robert receives a package with an idler arm in it, apparently from Ben's dad. Further on Robert is in the Thunderbird starting it. As Ben is walking up, he says "sounds good", then Robert drives off. All this implying that an idler arm is part of the engine, it is actually part of the steering assembly.
