Jonb, Thanks so much for helping us out! We were in a jam, with no rear-end just days before a 3 day event. In twenty years of buying Viper parts and dealing with Viper people, I can honestly say you have always been one of best best people in the business and the Viper community. Thanks for being there for all of guys that turn our own wrench. My son's and I are very grateful your business is surviving in such tough times. Now that were slowly getting back into racing, we will be turning to you for our Viper parts supply line. Sincerely, Todd
