Greetings, I am wondering if there is a way to tell without counting if my Dana 80 rear end is a 35 or a 37 spline count. 2002 Quad cab long bed 2500, NV4500, dana 80 with 3.55 gears. I'm planning on ordering a locker soon which is another issue in it self. Appears there are not many options for this rear end with 3.55 gears. If anyone has suggestions I am all ears. Planning on a lock right by power trax.

 

i just talked to a guy at gevos rears in gears yesterday and he said they are a 35 spline
