Broken lower hatchback window GASKET/SEAL

Hey folks,

Last week in Wisconsin, I backed my Prius perfectly into one of our garbage containers - which completely shattered the lower hatchback window. Now, besides being funny (to you all), I've come across a problem. I purchased a used window but I can't seem where I can buy new gaskets/seals for it. The old ones have glass shards sticking to it. Can any of you help, either to identify what it is called or better yet, where I can purchase this at a reasonable price?
