I have a 1986 T Top gt sittting in the garage in pieces. Most of the interior has been damaged by the chronically leaky T roofs which are complete but have both seals worn and dried out. I am considering three options at this point;
1. Seal the roofs shut with silicone and deal with them some other time.
2. Use either mustang or camaro seals and try and replace what is there
3. Disassemble the T Top and weld in the missing roof structure.
What are other people doing? There seems to be no supply of original Fiero seals. Is this a part that might be reproduced at some point by say the Fierostore. Unless they have been replaced already anyone with T roofs must be wondering what to do when their seals give up. Curious if anyone has any suggestions.

which of your seals are shot?--do your tops rattle when you drive? are your P-seals gone? where does your tops leak at?---a majority of the problem may be the end caps if the holes that the top latch into are worn and your tops rattle that would contribute to your leak---the door seals can also be worn out--I got a set off a "donor" at pick and pull--they all fit the same way you will just need to make some cuts for the top side--when I had my p-seals out my roof leaked badly--GA Fiero Club has a low cost fix, check their web site. T-Tops Parts and Appraisals has a "diagnose leak" TIB too---you shouldn't have to do anything radical at this point-hope this helps

Its the main seals that the glass sits on that are dried out and cracked. Both sides leak at points all around the perimeter. I am redoing the interior and dont want to have the new parts damaged by leaky tops. I am willing to work on the issue but Having no supply of replacement seals is a discouraging way to bstart.

I don't know about if they are cracked but we used a "moose" that GM sales for door seals on my son's 300zx t-top and they are like new. They say it isn't for restoring seals but it works. Just do it on a warm day and leave the tops off all day. On his seals there where little holes in the seal to let air out of the inside. We even sprayed some in there. Seals look and feel new now.

I am planning on a set of Mustang or Camaro seals. I havent installed the T top parts yet. I got new locks for the glass sections last week. I am gonna score a set of new door glass seals while they are still for sale at 'reasonable' prices.

I found the writeup about using 3rd gen f82 fbody seals but only some mention of using 70s mustang II seals or 80s 5.0 parts. Any of these adaptations would probably require cutting and joining seal sections which concerns me a bit. I know that Infinitewill had some issues with heat causing some early versions of his trunk seals to release over time where they were joined at the corners. I may be wrong but I think the person who did the camaro seal conversion may have passed away. I would be interested to hear if anyone has successfully adapted a set of seals and how they worked long term.

Good thread! I recently picked up a '87 GT that had been sitting for x amount of years. The T-Tops leaked so badly the passenger side floor bad has some rust. A lot more than usual. The "drip edges" are gone. Not sure if it's the same as the "shingle seal" on the T-roof exploded view page, but I could definitely use the drip edges to start with. There is a gap on driver and passenger side where the frame seal meets the seal on the glass. Right hand corner on both sides. Hope that makes sense. I'll be looking for the same solution.

Anyone know where I could get the drip edges?

Here is a thread where one guy used a Mustang seal, and the other member used a CAmaro seal. Both had good results. You need to read these threads if you need new seals and don't have $900 to spring for a NOS pair.

I checked to see availability of the alternative seals. CJPony parts has the 87-88 seals recommended for about $51 each and Dr Sunroof has the camaro ones for $89 each so not much difference in price. It sounds like the camaro ones might be NOS while the mustang are reproductions. I went out to look at the car after reading the how to threads and am starting to see how the weatherstrip is supposed to work. For the cost I think it might be worth trying a set of new seals and modifying them to fit.

I would try the mustang ones. The materal may be newer since they are repros- eg less prone to rottng.
