Eleven years ago I was a chassis design engineer. My oldest drawing of a current part was released in the 1930s, I think it was 1936. Part number was B60 (I think), a steel wheel nut.
Oh, and we are kicking things around (in a very general sense) for the 2010 car, which will have a life of up to 8 years! I wonder if we can we get a B60 released for it?
