Paul,
I use the tonneau most of all. Whenever I leave the car, the tonneau goes on. Saves the leather, and anything else that is typically rolling around the floor. Those black seats get damn hot in the sun.
As for the 18's
I don't have any decent pics. I will however be competing in the Clipsal rally in a few weeks and they will be on the car. I'm thinking of doing a blog for the event, just for fun, I'll keep you posted. You should have come over for it you know... just the place to stretch that mighty engine of yours..
Merv, Wazza (QLD Pres) made a hard top for his Harrison, and did a really nice job of fit and finish. I know there was a lot of faffing around to get it just right, but in the end it was and looked great. Maybe he can chime in with advice.
