don't get the TC gaske from ford it's 10 bucks, you can got to oreilly's and get the TC kit and get all the gaskets you need (SEE PICS BELOW)..
also the kit for the upper is cheeper at oriell's also it's just there web page doesn't show the correct set so I spent a extra 10 bucks at the Ford dealer because of this.. the kit is 14-16 at most auto parts stores (pics below..
