I'm planning on running a zc tranny in my 89 civic and was wondering what axles should I run. I don't have the shaft so I heard that I have to hybrid my old axles with the inner joints of a 90-93 integra axles. Anyone know of a better way to go about this or is this the way. One more thing, I heard the final drive of the zc tranny is at about 4300, would that be a big problem to me on the highway? It's not going to work my motor now is it? Okay, thanks for your help people.
