Wow, fantastic video! Thanks for posting Bill. I think it might be Group 5 though, as opposed to Group 2. The BSCC used Group 5 from 1966 - 1969. Group 5 allowed more freedom than Group 2. Group 5 was used in New Zealand from 1968 to circa 1972. Group 2 was used during the 1966 and 1967 seasons, introduced by MANZ alongside the Allcomers, as they wanted to get the cars back closer to showroom stock.
