You need the 99+ coolant tube that goes from the waterpump nipple to the back of the engine. My '98 didn't need the new 99+ nipple, but the 96 and 97s usually do because it doesn't mate up with the 99+ coolant tube. The new combo relocates the tube from going directly underneath the lower intake to the driver's side inner head wall. If you have it apart and can't wait for the real deal, I've seen some guys use a flexible proper sized radiator tube with clamps in it's place, but to me it doesn't seem as permanent as the non-flex type.

the flex tube i used is coolant hose, its made for it. mine has at least 10K miles on it since the original intake swap and no problems. its a much easier solution to tapping out the nipple, which is a pain.
(2nd clamp isnt tightened in this pic but it should be)
