I started on this in 1982, after purchasing a frame for $200.00. After finding 57-58 tank shift tanks I knew it would be a 57. Over the years, I have been looking for parts.
In 2013, in Davenport, I found a speedometer, one of the last, hard to find parts. It's still in sanding primer and awaiting the decision on the final color, although I'm leaning towards pepper red and black.
