I built a CSX a few years ago and as far as I know I am only 1of 1 Shelby American built street versions ever made in fiberglass.
It is original Guardsman blue, no stripes , no side-pipes but it does have a hood scoop ,roll bar and functional
oil cooler. It has a street dash, ash try, radio,windshield wipers,15" halibrands and a glove box. I have less clearance than my SPF buddies but they love the sound and look of my car. Plus with a 427/ 525 ponies, my times at the strip are just in line with my friends. HRE swears to me that if I ever were to go to side-pipes I wouldn't gain a single hp.
Of the 3000 series cars only around 37 of the 350 original cars were S/C s. Most street versions however were converted in the 70's and 80's to S/C's. At this last years Barret-Jackson auction an original "untouched" street version actually went for more than an original converted S/C.
Good luck with your choices!!!!!
