Spicer and most u-joint manufacturers make them. Mancini carries the Spicer ones, but if you go into any "knowlegable" parts store they should what you're asking for.

HEHE! What stores do you consider to be knowledgable?

A place where someone you know personally and trust works or owns, that way they know if they mess up they'll never hear the end of it :D
