One thing to note is the 4cyl Dakota transmission is a 2wd ax-15, the 4cyl Dakotas didn't come in 4x4, and the v-6 and v-8 Dakotas used the NV3500 with the non-removable bellhousing, the trans output might be clocked a little more than a Jeep trans, I never compared them, but unless your swapping in a V motor it really wont matter. (note all the above info is for standard trans vehicles, I make no comments on autos as I haven't pulled any yet)
