The Black foam that insulates the boot from the weather on a friends van has weathered over the years, I think it started out as 9mm wide and 6 or 7mm thick in Black ( now down to 3 or 4 mm thick). I would like to help him replace it. It is probably similar to the Bunnings item below that is thicker.

Have your purchased said foam ( 9 x7 Black) and where from.

Thanks
