ArasB,
I think Bill is right. I'm far from the foremost expert on Cobras, but I don't think there is anyone around who sells a body of a Cobra you can just drop onto an existing car frame. All of the Cobras you find here have their own tube frame chassis. As Bill stated, the "donor" concept is using the mechanicals of the car, not it's chassis.

For SO many reasons, you'll be better off doing a Cobra with one of the many existing makers and their chassis. There are many owners in Illinois, in fact there is a Windy City Cobra Club here on this forum. I'm certain they can help you figure out how to properly register and inspect a properly built carb'd Cobra.

Best of luck

Steve
