It is really coming along great, Craig!
I was wondering if you might know about this little peculiar detail in the cockpit, as seen on John Norman's incredible recreation. If you look really close in the image linked to below, you can see that there is no bolt going through the clamp to hold the fuel drain funnel in place. This isn't a mistake, and is exactly the way the original Spirit of St. Louis has the funnel secured as well. According to John Norman, it has been speculated that perhaps that was in order to allow Charles Lindbergh an opportunity to pull the funnel forward in order to 'relieve himself' during the 33.5 hour flight from New York to Paris in May 1927.
In addition to the Lukenheimer Fuel manifold, this photo also shows the magneto booster that is mounted down low, directly in front of the control stick. Also note all of the "rash" on the various parts, which John Norman did on purpose to match the same wear & tear as seen on the original.
