I picked up a set of disc brakes from a 79 lincoln Versailles. I just read that the lower ball joint tapper on the spindle is larger than my 68's and that I need to use the ball from the Versailles?! Can anyone confirm this? What do I do to resolve the issue if that is the case. D. Hearne, if you are out there... can you help me with the "problem" if there is indeed is a problem? Anyone, an assist here is much appreciated.
