hey I'm new to jeeps and I'm purchasing an 87 with a 2.5 and a 4spd on the floor next week and I'm wondoring EXACTLY what needs to be done to put in a 4.0. ive done engine swaps in chevys but its a little diff obviously and I'm wondoring if what components i can use that are stock. id like to keep the 4sp cause it has 4.10s and i plan on eventually running 35's (yes i know the axles won't last long) is is possible do i have to modify the tcase in anyway?
