There is at least one that came from factory with a roll cage. It's been at one of our monthly so cal meetings a while back. I'm not sure why they did it or who owned it. Alan or one of the other so cal guys should remember. I think my bro-in-law(shelbypart) got some pics of it.
Also who could forget about the shelby vans. Unknown production number. I think the one my brother in law saw and got pics of had a dash plaque on it. I don't remember what number he said it had if he even made it out. Used to be right here in Temecula. He also saw another one on the freeway that was turned into a work car and was beat up and missing almost all the Shelby stuff.
There's also the 88' and 89' CSX proto's. Ithink there were like 5 or 6 of the 89's. Not positive.
Can't think of anything else off the top of my head right now. I might think of something else later.
