Sorry I did fail to mention it was a ZF application. It is really more of a "look" thing. I want to look as original as I can given the kit I have decided to build. (RCR, ZF, SB ford) I think sometimes the original look might not look as good as the new stuff. Like braided line with red and blue fittings. Some like it, some don't. When you see CV's on one car and halfshafts with universal's on another, which looks like the guy built the best car and stayed within the "correct" look guidelines. Remember the guidelines are for replica's in the first place!
