An old 'home movie' 8mm converted to digital show's CSX2001 with BOTH "AC" and the early "Cobra" emblems, one above the other! The video's are posted on SAACforum.com Some other interesting details are also shown on that car. Hood scoop, roll bar, side exhaust exit under car. Good stuff.

CSX3275 pictured above? Can't be, slab side street car wouldn't be in the 3000 range.
