I found a source for ZC intermediate shafts
 

I called Raxles yesterday to order my axles for my B16. I talked to marty and he said that his son was putting a zc into his crx, and I said that some people were having trouble finding intermediate shafts for the zc. He said that he knows a guy in Germany that can get ZC axles from a junk yard for cheap. so if you need ZC intermediate shafts call Raxles and ask for Marty:

888-257-8192 or
800-257-8192
