hey guys. i am playing with the idea of a posi in the back of my 2500 diesel. it is a 3.54 gear.
i did some looking on two places and did not find too many options.
it seems that the dana 60 up front i really need to know the spline count.and the dana 80 in the rear i think has 35 but am not sure and carrier wise some told me the 80 has 70 guts in it?

i am tired of killing the right rear tire plus going up to snowmobile with chains on a posi would be even better with the tire chains on.

anyone put one in their open diesel 5 speed? i was hoping for the type thet installs inplace of the spiders in the open rear with no removal but from what i am seeing it is not made for my 80.....
