That came out Great!!! I love the color! Just an FYI thuough, that frame was never sold as a duck or through Bird, it was exclusively Sears sold and labeled and its the later/last one ones made (they did not call them Drovers, but everyone calls them that) up 72/73 timeframe.
The engine is the '80's version so if the code starts with a 2 Its a 1982. Have fun with it!
