Hi Cameron...good to see are looking at two bars.....too many of us dont consider our partners safety.
As to where to get em...again I can recommend Don Pilling at Snake bite ... 07 5529 0877.
Don makes the single hoop bars both left and right versions. Mostly in polished stainless but discuss your wants with him.
I have a full width bar made by Don and cant fault his workmanship. I supplied Don a thin 200mm X 25mm LED strip light to insert into the middle of my bar as a high mount stop light. Turned out bonza.
Mind you...Don lives at the Gold Coast and is a Queenslander, but I'm sure would help you anyways.
