You are correct that these are being made currently today. The guy who came up with it lives in Plano, TX and the photo you posted is from the Running Horses fountains in Los Colinas, TX aka Dallas.
The owner of the company who is building these clones spoke at the Tulsa Shelby meet a couple of weeks ago and there are two types being made. One with their standard engine and the other with a SCJ. He was bragging about who all has put an order in for one and the only name I remember was Kidd Rock a rapper because I thought it would end up on a music video.
They ran the cars in the road rally and on the drag strip. VERY UNIMPRESSIVE times. These things cost $150K and they were 13 sec cars. My stock 429CJ does that and I didn't pay $150K.
