Don at advan carbon sent me an email in regards to a carbon fiber hatch for the ceica hatchback and the supra. He will be using an 84 hatch for a mold. price will be around 700-850 depending on the amount of people who join.
Might want to put wirysage and don in contact with one another, since this should bolster both group buys. Don will hopefully just have the option of including a seal or not since I know some of us will buy our own while others, and those outside the forum will want to have it included with the hatch.
eww. I hope it's left completely holeless and spoiler-less and left up to the owner to customize it for his/her look or use. I am sure there aren't going to be several hatches made, and I am also sure there are people who AREN'T going to want duckbills or '83/84 window shade types, etc etc. Can't please everyone, so like the hood, best to just leave it "stock", and since this hatch is not just for Supras, but for Celicas too, stock would mean with no holes for spoilers.
