I make them as a complete kit with brackets et al. You can finish to suit after fitting to your car. That is another one of mine pictured, fitted to a car that didn't have one. Chrome is expensive and I like the black look. I haven't seen any originals with two roll bars, only a couple of odd wide ones.
