Thanks Peter for the link - have downloaded a copy and have been ploughing through it.
One interesting change for this year is that for cars from period F (post 1961) onwards, harnesses must be 6 point, good for the sale of seat belts no doubt.
Must go out and check the WSM as I may be taking it to Spa this year, and I know how fussy they are about such things.
May have to change the seat as well......or perhaps stick to the Elite.
