There was only one Shelby GTS S/C( 1997) version made. There were 19 of the 95-96 Shelby CS Gen 1 made in three colors. White with blue stripes, blue with white stripes and one black one. The front grill was cut out (both models) and opened up to give it the Shelby Cobra look. The stripes were similar to the Cobra. These cars were done at Fitzgeralds Motor Sports in Laconia NH. Dan Fitzgerald is a personal friend of Mr. Shelby. Fitzgerald Motorsports did the Shelby conversion with Carroll Shelby's collaboration. Orinigally, 50 of the Gen 1 roadsters were to be built. Then when the Gen 2 GTS came along, they were going to do 25 of each. However, due to Carrol Shelbys Health condition in 1997/98, all worked was stopped on these cars. Thus, only one GTS was produced. I have known Dan Fitzgerald since 1995 when I purchased my first viper from him. This is how I met him and stayed in contact with him for many years. When the first Shelby GTS Viper was made, Dan offered it to me. I have owned it ever since. A few years ago at VOI in Detrioit, there was a slide show of collectable vipers.There was a white/blue Gen 1 shown. I later had a conversation with Ralph Giles on on collectable vipers and he said your GTS, " IS A KEEPER"! So I return it to its original Shelby form (removed the bolts ons) and then added a 09 ACR tp play with. I now Show the Shelby GTS Viper at Car Shows. It has been featured at some Shelby themed shows as well as being At Shelbys Headquarters in Vegas during the VOI 5. I hope this helps. I will try to answer any questions about these cars. I have many photos, and a couple of the original Shelby Brochures as well. I also still have Contact with Dan Fitzgerald who may have all the answers.
