96-99 grand am 2.4l engine swap

Hi looking to see if anyone out there has done a 2.4 motor swap from a 96-99 I have a nice low mileage 96 2.4 I would love to put into my 99. The interchange book lists 96 all by themselves, but I was told by someone that it will interchange, that you have to switch all the sensors, the injectors, & drill and tap a hole in the rear right side of the block for the knock sensor. If anyone has done this or tried to do this, let me know thanks.
