* The "C" in Dana 35c does not stand for C-clip. The "C" stands for custom. They are custom because they are shipped incomplete from the Dana factory to Chrysler. Final assembly was done by Chrysler. Dana 35, 35C come with 27 spline axle shafts that are 2.625" in diameter, they are know to be a weak point for severe four wheeling and over sized tires.
