Scott,

I love these wheels.
Try this link: [link=http://www.darrolcady.com/Accessories/accessories.htm]http://www.darrolcady.com/Accessories/accessories.htm[/link] and scroll down to the Streamlined Racing Wheels. These are great because the O ring cannot pull out of the two halves because of the "T" slot. Right below these are the Pizza cutters that most guys use.
