What is the best way to find something you have misplaced?

At the last work day, it was found that spacer that is part of the lateral control assembly could not be found... Now I ask you... What is the most reliable way to find it?

Make a new one! And that is exactly what has been done. Al had a new one made a day or so after the last workday, so we can be sure that the original will be staring at us the moment we finish the assembly of that last bogie... Murphy's law pretty much guarantees it!
