you didnt mention the color of your 31 sport coupe
the only colors Ford offered for the 31 Sport Coupe stripe were
Straw,Hessian Blue,and apple green
the standard color for the wheels were Black
of couse the argument goes that Ford would paint your stripe and wheels any color you wanted at the dealer level
the only 31 cars that had orange stripe and wheels were the deluxe phaeton,deluxe roadster and the convertible sedan
the 31 Cabriolet had the orange stripe ,but the wheels were black standard
all with the Bronson yellow and Seal Brown paint scheme
