being an 8800 GVW rig theres 2 options those came with, the NP241-DHD and the NP241-DLD either one will interchange from a cummins or a v10 powered 2500 or 3500. the 360 gasser 2500's and half tons have different spline counts i believe (dont quote me) and honestly are not worth the hassle of making a frankenstein transfer case. the main difference between the DHD and the DLD is chain/drive/driven gear width. most 1 tons had the HD, and oddly enough, even if its a diesel, the 2500's mostly came with LD's. durango/dakota case is a no-go, those were NP231's, and would eat itself alive in a V10 powered torque monster. the 241 is cake to freshen up. ive done three and they literally take maybe an hour to do. theres 1 synchro, and the oil pump assembly is plastic. thats really the only things that may be troublesome. pulling the bearings and seals to replace is easy as pie. (im hungry haha) the rest is very self explanatory and theres tons of helpful sites that can assist you.
