Have you considered B&B Manufacturing (formerly LA Exotics)? Bryan Anderson and Barry McGill moved their manufacturing from Los Angeles to Granby Missouri (about 1 1/2 hours east of Tulsa or about 15 minutes south of Joplin, Mo).
B&B produces a high quality product (very strong frame and hand laid fiberglass), plus they are great guys with 20 years experience . Absolutely men of their word, eg: they do what they say they will do and more.

I have had mine for almost 4 years and I have driven it very hard at race tracks. Although I have had problems in the past none of my problems had anything to do with the structural integrity nor the manufacturing of their Cobra replica. I highly recommend these guys
