In reality, although Shelby American wasn't pumping Cobras out the door as rapidly as they might have liked, neither were they too excited about adding a lot of options to the cars beyond the standard stuff, such as radios and luggage racks on the small-block cars. The big-block cars basically had no options. Some people who ordered them asked for roll bars, wider rims, and sidepipes from the factory, but no more than a handful of street cars were equipped this way. Shelby American found out quickly that it was too time-consuming and costly to install these options at the factory, so they made them available through the dealers, and advised them to sell the customer the car first, then add the equipment later. In this manner, Shelby got out from under various cost, quality-control, and warranty issues. And it's why 99% of the cars that received these modifications got them after delivery.
