it may not be the seal. i've had leaks through the fasteners on the glass. also, there was a mod involving drilling 4 holes in the roof panel at each of the corners, just at the outer edge of the main seal, which allows water pooled around it to drain off.

Mine was leaking very bad this year and a new seal turned out to be a waste of money. I removed and replaced the seal and the water came thru even faster. Turns out the tracks have bolts that hold them in place from underneath as well as the rivets on top. You have to drop the headliner to access them. If they have been leaking thru the bolts it will be obvious. The bolt heads will show signs of corrosion.
When you remove the old seal it will be extremly likely that one or more of the rivets that hold the track from the top will be rusted clean thru and the track will move around a bit. They do not pass thru to the interior. However when removing the old seal you will disturb the 20+ year old sealant on the bolts. Now you have a good leak. The fix is easy.
Remove the bolts taking care not to twist them out of the track, a little penetrating oil will help. I used 3M rubber caulking/adhesive strips to ball up around the bolts, its real similar to the stuff around the wind shield. I also added a little RTV to the threads just for good measure. Reinstall being careful not to over tighten the bolts, squish the sealant out around the bolt head and washer. Add some on the bottom side if you feel its nesseccary to get a seal. I totally covered the bolt heads in my car, you can't even see them. If the rivets are shot you can attempt to drill out and remove the old one. I opted to drill my own new holes and use small 1/4" long rivets. Put the RTV to them upon installation to help fight corrosion. Ensure you do not try to drill all the way thru to interior. At the rear corners there should be a drain hole, mine were clogged with sealant from the factory. Clean them out with a piece of stiff wire. When installing the new seal be sure to use lots of vasoline or something suitable. Do not be stingy with it. Dropping the headliner is about the worst part. Have a friend handy because they are delicate and break easily. Hope this helps.
Good luck 88Ironduke

Before you go throught the trouble, get some silcon spray and soak the rubber well with the spray and rub it in. The silicon will cause the rubber the swell some and may eliminate the leak. Remember the rubber is probably original and has probably dried up some and shrunk.
Otherwise yo will have to follow 88Ironduke above suggestion .

thanks for the info. The seals I'm talking about appear to be strips of rubber between the roof frame and the roof top. I haven't looked at them yet, I just saw in the repair manual that they were there and figured I'd try and get new ones sine they are 23 years old and the roof leaked bad before I retired the car back in 96.

If I am reading this right, you are talking about the seal that sits between the roof skin that the metal roof panel. that is a tyor of rope seal, and it is not available in the original size, but some have found a close enough source. you need to remove the whole roof clip to install them, they sit just to the rear of the windshield IIRC. Now if I could just remember the thread that discussed it.....

I'm having the same problem. Water leaking in through the sunroof opening - but the source of the leak isn't the sunroof. I firmly believe its coming in from the windshield/top panel joint. Very interested in comments to this thread.

Park the car outside in the sun and let the roof get good and hot before trying to remove it. It will make it a lot easier to remove. Be very careful, the roof is fragile and the most common place to break it is the thin area that goes around the windshield.

OK so loosen the two front fenders, remove the windshield cowl by the wipers and? Do you need to take the headliner down inside the car? Anyone out there done this and have any other words of wisdom before I screw something up! Thanks!!!
