Brandon,
Mike Marshall is building one up in Florissant (you can reach him on the ffcbora.com forum), and there was another guy in Town & Country building one too...he also has a mid-states roadster in Cherry Black - but can't remember his name.
I don't know of any completed ones in the area, but WildBill3 (ffcobra.com) is trying to sell his completed Factory Five coupe in the K.C. area.
If you get one set-up with air conditioning, I think you will be very happy with the car. They have a longer wheelbase then the roadster and offer a better ride, expecially on the track.
After helping finish the one the OCC raffled off this year, I got to see a lot of the car, and appreciated the differences in it compared to the coupe.
