After a few hours of hunting and stripping the interior out i found the problem. I eneded up removing the lower half of the dash also







Under the battery tray i found this hole



What has happened is before i owned the car someone used a long bolt to hold the battery clamp and it punctured the lower skin. Over the winter i bought a new clamp and the correct bolt so the hole was no long plugged and thats where the water has came from

All sealed up now tho
