Phil,
To check out a site that is based on the rebody concept of an existing Sports Car try
www.cobrasnvettes.com . I offer a Cobra inspired body and floor tub that bolts directly to a 3rd generation Corvette 1968 to 1982 and the 4th generation Corvette. The bodys are longer and wider to accomadate the 98 inch wheelbase but the C4 is a 1/2 inch shorted wheelbase but the body lenght is the same. There are many performance suspension upgrades available if desired but already very respectable handling and weighing 1000 pounds less than the Vette does not hurt performance either. It is a very basic and easy task to unbolt Vette's 8 bolts and replace new body kit with same 8 bolt locations. Thanks Jeff C
