I guess I will be keeping those CVD's. Well it has the threaded hinge pins on the rear hubs already and the rest are captured like the current ones. So the only real difference is the shock towers then? What is different about the shock shafts? The rear wing mount is much wider on mine than the current one, the wing mount spacers that come with the kit make it like the newer one? Just wanting to know if it is worth getting the upgrade kit so people who would be driving what is currently available for sale now or should it still drive the same and just leave it alone? I remember reading about earlier models having broken arms and hubs and stuff. I was wondering if these arms on it are those old ones. Then I would just buy newer ones to replace them.
