Epi M50 Woofer repair

I just picked up a pair of EPI M50 speakers.One 6 1/2" woffer was frozen,turns out the magnet plates shifted.I had to remove the spider to free up the cone and coil which are still good as is the surround.Does anyone know where I can get a replacement spider from canada or elsewhere? It is a 1"x4"x about 3/8".Probably material is around 2mm thick.I can pick up replacement woofers for cheap but I would like to keep the originals if possible.Any help is appreciated.
