One thing I am not wrong about though, is in this article they state that Rayborn hit the guardrail. There was no guardrail near Champion at Pukekohe at the time of his accident, there was white wooden fences on both sides of the track, and the steel guardrails were not installed until the late `80s as a result of John Osbornes RX7 Sports Sedan accident where a part of the timber fence went through the floor of his car.
