In the current issue of KIT CAR MAG (January 2005) page 59 is a very interesting version of a hard top. The rear of the top goes all the way back to the rear opening boot lid. The fuel filler then goes up through the roof. Usual design but looks effective.
Phil , further in the mag at page 77 is a article on air con installation. I'm seriously considering a variation.
