I am to the point where I am going to put my 71 Dart together. I really want the Passon 5 speed but they seem as though they aren't going to be available for quite some time. I was thinking about putting an aluminum 4 speed together with the Passon 18 spline OD kit but would prefer the 5 speed. The OD kit is also not inexpensive so even though the 5 speed is quite a bit more I would rather bite the bullet and spend the money on the 5 speed put it in and be done with it. What I would like to know is has anyone run both the Passon OD unit and the 5 speed to let me know if the tradeoff is worth or not worth the difference. I do plan on driving the car alot and only want to do this once.
