Convertible Roll Bar

Does anyone have pictures of a roll bar that is in a convertible? Especially an early-a body. I was looking at the drag racing rules at some of the tracks nearby and they require a roll bar for a convertible faster than 13.99. I have never raced before but I'm sure my car could be faster than 13.99. I know it is a safety issue. I just want to hit the track every once in a while to see this baby run legally on a stretch of asphault. The look of a roll bar in this car does not seem appealing. What about Mopars at the Strip? Did they allow non roll bar convertibles that were faster than 13.99?
Thanks
