I'm curious about this also. My 88 GL has the same problem. The rear pad
and insulating cover over the engine hatch is wet by the right rear
window each time it rains. Doesn't appear to be from the rear hatch, but
the rear side window somehow. I did pull that plastic locking bead out
because it was so faded and broken in places. I wonder if this has casue
d the leak.
