I am going to do the Viper output shaft upgrade to my t56 and I need to find someone who will sell me a slip yoke that will work with the 30 spline Viper shaft. I was told that spicer does not make one (but not sure of that) and please do not even mention D&D because they will not sell anything related to their Viper shaft kit seperately. Not even the 10 cent lock rings that hold the reluctor gear on!

 

Contact Denny's Driveshaft.... they stock them.
