Surely somebody on the list has seen this.  

I opened the rear hatch on our '87 Westy last night, after a mild thunderstorm, to find that the cushion and engine cover were sopping wet.  I can't quite tell where the water's coming in from.  I did find one spot of seam rust on the inside of the roof where the A/C lines go into the ceiling, but it and the A/C lines seemed pretty dry.  Does this ring a bell with anyone???  Is it leaking from under the pop-top???  Bad door seal???  I'm stumped.

TIA!
