If you use the v-faqs you can find 2 seals at alot of places around here, I went to a place in bloomington off 35w. It's pretty easy to do it and when you do replace the seals then you know your all good.

and use both of these links and you should have everything covered, it's all pretty simple to do. Should get a block off plate when you have the TB apart.
