Or you can buy them http://www.fiero.nl/forum/Forum4/HTML/048607-16.html#p604 - Here for $95, going up to $109 in eight weeks.
I betcha the shipping charge would be lower as well.
[EDIT] There's actually an offer now of free shipping to a US address for any orders placed within the next week or so. I know we're not in the US, but a discount for Canadian shipping may apply as well. Check out the link.
Aw heck, here's the link from the http://www.fiero.nl/forum/Forum4/HTML/048607.html - Pennock's thread copied below...

Well, as promised I have a major update for you today (10-02-2010 07:12 PM). Since today is my birthday, I decided to give all you who have supported my trunk seal project a big present. Today I am announcing the GT Trunk seal Gen III. with the introduction of my fully molded corners. A select few of you have been aware that I was working on tooling for a superior molded corner and we now have begun to make the tooling for the final production corners. Although I have been very happy with the shape of the main extrusion of my replacement seal, I have been very frustrated with the amount of effort that I have had to put into the mitered corners, specifically the bonding agent used in the Gen I version. Initially the seal corner looked acceptable but after a very hot summer for some of you we are starting to see the limitations in the original MEK based bonding agent. Some of those original Gen I seal have had corner failures in the bonding. The new bonding agent used in the Gen II seal gives a much nicer miter joint but even it can be very time consuming when assembling the final seal. Further the seal, although far superior to the factory unit in materials, does not look as original for those wanting a more concourse replacement. That brought me to a conversation with several of you that are looking for a more original looking seal. Frankly, I think the corners on the OEM seal look pretty rough on many of the original seals but they have held up quite well. I looked into having a fully molded seal tool made similar to the factory piece but the lowest estimate I got was $68K!! with a minimum order of 5000 pieces. Not in my lifetime!
So I started doing some mock-ups of a molded corner plug that would exceed the factory corners but allow the use of my existing main extrusions. The solution I came up with has turned out to be far better than I thought it would. Below are the samples we have made and a detailed close up of the finished joint.
This plug will allow me to make solid corners that have no miter joint.

Joint bonded in place the hairline joints are nearly invisible

The plugs will also allow me to use my existing main extrusion

Most attractive about this plug is that it looks better than the factory corner, IMHO while being close enough for show cars as well as daily drivers.
This new corner does however come at a price. The Gen III seals will see a very slight price increase to cover the cost of the new tooling. I think it will result in a superior product that is worth the extra effort, investment and marginally higher price. One other nice benefit is the ability to retro fit my previous seals with the new molded corners for those that would like to upgrade.
The new Gen III seal will sell for $109 + the same $15 shipping as before but unlike my build to order method which lead to some rather long lead times on occasion, I will have these seals on-hand for immediate shipment once in full production. Because I am being forced to raise the price on the Gen III seals I will make this offer:
Anyone ordering seals before the Gen III seal goes into full production in approximately 8 weeks (lead time for both the tooling and plugs) will pay the lower $95 + $15 shipping price of the Gen II seal for the Gen III seal. Any orders placed and paid for in the next 14 days will also receive free shipping making your net a flat $95 shipped to the US market for the Gen III seal. If you would prefer a seal be shipped immediately, the current price of $95 + $15 shipping to the US market will remain valid for the Gen II seals and should you decided to send your seal back to me for retro fitting with molded corners in the future, the seal can be updated for $20 + shipping (a very slight discount can be given on shipping if I reuse your shipping box).
I can't thank all of you enough for the support shown to me on this project!!! With over 100 seals shipped I am nearly half way to the break even point on my investment and with this new corner tooling we will have a fantastic replacement for the now non-existent OEM seal 
Thanks again guys and girls!
Will
