I have an old (1970) book by David Hodges which gives the frontal area of the Mk2 as 15.8 sq.ft., compared to the J car's 14.8. Does not give the drag coefficient, unfortunately. I would also think 0.35 is about right. I'm sure it wouldn't be better than that; possibly worse for a 40 in racing trim.
