B Beep: There was a 70 Barracuda Gran Coupe convertible 383+4 at Spring Fling a few years back. Burnt Orange with burnt orange interior with the C15 option. It had burnt orange belts with the seat belt light. The C15 belts were available on A,B,C,E and Y body cars, but the belts themselves are not accuratly interchangable between the body types. They have different part numbers, belt lengths, etc.
