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 known to be a weak point for severe four
wheeling and over sized tires. |
