I don't think Ford ever listed a 1937 Ford coupe as a "business coupe",but information in V8 Club restoration book shows the Model 74 (60hp) standard coupe as #770-A (5 window) the 770-B was same body in Deluxe trim passenger side tailamp,chrome windshield and grill (unlike standard painted )and running board trim moulding,also Deluxe interior banjo wheel,etc. The 720 Club Coupe was available in Deluxe version only it of course had rear seating.With rare exceptions the 60 hp was available only in Standard form or in some commercial models or special order.
