"Attached are some photos of another Roll Bar in Oz. Notice how the bar is set further rearward by cutting into the rear cockpit rail (easily reversible). It also has rear bracing back to the wheel arches and a cross rail for fixing full harness seat belts. It has a removable front support that is not shown in these photos (owner only puts it in for circuit events). Unit is removable, relatively easily. It was manufactured by Brown Davis - https://rollcage.com.au - Installed cost was around $A2,000".


Again, vintage period correct, perhaps. Only acceptable today if it was grandfathered back in the day, and kept in continued service with a valid racing log book with no time gaps. It would otherwise not be acceptable for competition today (by most race sanctioning organizations) due to lack of fore/aft braces near top of the main hoop.
