turns out the struts at the top of the boot (the end that screws into the body shell) has two pathetic seals that were leaking water into the car. this was coming in the car from the rear seatbelt mounts dripping on the speakers and running down the inside of the interior onto the rear slam panel.
so any one with a leak in this area check the strut seals.
i replaced mine with a large piece of flat rubber cut to the same shape and size of the strut mounting plate. this seems to of worked. hooooorrrrrraaaaayyyyyyy!
