Circa June, 1986 I go to a car show at Mile Square Park with Bob Whitely. Bob tells me how to tell this 1940 Ford from a 1939 model: "Wipers are at bottom (not the top), the grill has extra side grills and the headlights have different surrounds. There are also differences at the rear with the '40 having chevron style taillights" knowing this kind of stuff vastly improves my street cred.
