CAMS have an eligibility list of sports cars for 2b Marque sports racing. For a
car to be added to this list there is a process. For the DRB GT40 to be added,proof would have to be supplied by the manufacturer that 10 cars have been built over a 24 month period which would put it in 2BII of limited production.Of course CAMS don't let you approach them directly and you have to contact a person who can present your case to CAMS.I can place you in touch with someone if you want to take it further.
