so this problem is fixed?
or i should say, you've found the solution?

funny, it says concorde on top, intrepid on the bottom.
lhs would be the same, if it makes a difference looking it up.
maybe run some water around with the lid open and see if it can get under the gasket anywhere.
look for water stains at the top edge that look like maybe water is getting by.
maybe the seal is going around your rear window.
just throwing some things out there.
don't know if ours are hollow, if they are you might get something stuffed into low/flat spots.

only the threaded posts come through the back of ours
you undo 4? wingnuts and they pull out.
might have a little leak around the posts.
have to pull out the trunk trim and see if leaks through the openings.

is it while driving in the rain too?
could have a spot corroded out from underneath even.
you'll have to pull the trim to find it.
and pull the lights out and have a look behind.

 

[yevrah]

just a thought.
some hidden spot behind the wheel well.
just thinking of things to check.

if it's while standing, then it has to be from above.
pull the lights and have a look.
look on the underside of the trunk opening edges for water tracks.
might have to get help and lay in the trunk with a light and close the lid and have somebody run a hose around the opening.
should leak if the seal is bad anywhere.
look for tracks starting from around the rear window too, as drips can run along body panels before dropping.
