Here you go. The link you have is a good seller, but don't get the old fat ballast. Get the slim ballast, I've had mine more than a year and they're still going strong. The slim ballast is also easier to find a mounting point in your engine bay.
I have them in my lows and fogs. He has insane shipping too. If you order right now... you'll probably have them by Friday.
