When you're actually doing the body lift, make sure you disconnect the fan shroud and any column mounted automatic transmission linkage. Maybe even for the manual trans if that's what you have, but I've gotten away without disconnecting clutch and manual trans linkage before.
My experience is that most will not need longer fuel hoses, but some do.
You will obviously have to modify the fan shroud, or get one with the body lift in mind.
Many do not have to notch the floor for the transfer case shifter, but some do. Not sure if the J-shift you have is more forgiving of this than the T-shift of earlier models, but it's something to be aware of anyway.
