Let's get this thread back on track...
Kenmer Cobra
Definitely speak to Martin at Kenmer Cobra. He doesn't self promote like others but he has about 5-6 cars on the go including a new bodied 68 Mustang with Coyote engine and IRS. His Cobra body shape is based on the DAX and he works closely with engineers so you won't have any troubles with compliance if you follow his advice. Ford/Chev setups, roomy cabin, custom suspension for proper wheel offsets, soft tops, big brakes, ADR approved seats - you name it, he can do it. You won't meet a nicer bloke, nor will you get the hard sell.
