No first hand experience, but when I go by the CCC garage in Enfield CT during the summer, a number of times a week, there always seems to be a few Cobra bodies in process, must have a good business along with other Custom work.
Among the hobbyists in CT, Walt Wosko, owner of CCC, has an excellent reputation. He's doing business in the family owned garage that dates back to the 40's & 50"s. At one time, the building was a Studebaker dealership.
