Becarefull with companies such as elephant and admiral, they are the same company. I have insurance with elephant and have found out it is void. I have a 95 n/a and they do not insure them, word of advice to any other n/a owners, Check what engine size they put down.
When renewing my insurance ready for the end of the month I noticed they had the engine size down as 2947cc. They are now saying that they do not insure the n/a. Luckily they have said that they will continue my cover but will not renew it as its their mistake.
Just be careful guys as, Check all the documents carefully.
