I just swapped mine over the weekend while installing the locker. I got the ones off of ebay. Another item you might need will be a steel bar and a large random sized socket. The CV will come with a bolt. It is designed to be threaded into the CV so you can pull the CV out far enough to get the c clip back in. Thread the bolt through a hole in the large steel bar, use the socket as a space to pry against as you tighten the bolt. It is a TIGHT fit. I thought I was going to break something. I got the two CVs for 120 USD shipped. They were brand new. Seem decent enough.
