sounds like the headliner needs to come down. Take get out of your way then have someone for water over the sunroof and see where that water is draining. depending how good you are doing body work you could use the panels from Russ and just pop rivet them on. painted up and a little silicon on the edges of the metal and the rubber seal will seal just fine. I think that trust is just a Mitsubishi mistake, its not getting sealed when it was built . and I think the valve cutter is a Mitsubishi patented thing also <img src="/forums/images/graemlins/wink.gif" alt="" />
