Well first off if you have a factory diesel than it has to be a 3/4 or 1 ton so either w250 or w350. If so than yes you should have a 32 spline np205. And yes the off road design twin stick package will work on a dodge but talk to one of the guys down there first before ordering and explain how its going on a dodge cause you will have to do some minor fab on the kit. Plus if you want to be able to run just the front axle you have to either shave your rails or get the ones they sell. Kit comes with all new everything so don't worry about the pins and you are gonna have to find a used switch from someone.
