Dodge NV-4500's used in 2WD applications has 30 spine outputs and the NV-4500 2WD used behind the Cummins Diesel used a 31 spline output
*************************************
On top of the transmission you will find a paper BAR CODE tag. All dodge numbers start with 'P' then 8 numbers and 2 letters; example P52108131AD which is a 1998-2000, NV-4500HD
GM NV-4500's have a 3 or 4 digit alpha code. The paper Bar Code top of the transmission is the only place that the model number was printed.
If you post or email me the number on your tag, I will tell you exactly what you have.
I primed my T Case with PPG MP-170 epoxy primer and then shot Cummins Beige.
