It depends on what your fuel rail you got I believe it’s the 96 to 2000 it would be the two studs and 92 to 95 would be the three studs I just removed all the studs from the manifold and put them in place where they needed to be for two studs. If you got the skunk to manifold I believe it’s ProSeries it has spots for both set ups a total of five holes for the studs just use which ever set matches your fuel rail
