Mike informed me that the factory is now back to work after New Year break and are starting my build. I confirmed with him that the scheme I posted above is available, so I'm getting that. I'm also having them make the speed brakes functional. Hopefully it doesn't take too long to get here. If it arrives by May/June that would be fine as summer is build season for me for the most part (too hot and humid). This will give me time to do a thoroughly documented build.
