Here is the new race installed. Remeber to grease liberally both the race and the race lip inside the head. The top race went in with no problem at all because it's much easier to keep the drift true coming from the top. I had to start and remove the bottom race three times before i got it to go in straight. It went in deeper and straighter after each attempt. Remeber do not force it. Just stop, remove the race and star over. Do not gouge the inside of your race cup.
