I just noticed on the '57 that some of the cars had a chrome protrusion on the top of the bumper that sticks up a couple inches. Look at the top photo on this link: http://www.imperialclub.com/YearByYear/1957/FactoryPromos/index.htm I started going through archives and approximately 1/3 of the 1957 cars I looked at have this, 2/3 do not. Is this an optional bumper or what? _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.
