It may not be a "kit" at all. Could be a "home brew" of a modified production frame and a store bought or one-off homebuilt body. There's more of those around than you might think! Think about all the "T" bucket and "32 roadsters running around that were built that way. And, if you think about it, some cobra kits are really nothing more than street rods with a sports car body. ( not that there's anything wrong with that!)
