Any second generation shifter will work, providing you have an existing one. Older model Intrepid's (99 and older I believe), the bottom metal bracket is different, worst case you swap bottom bracket's with you existing shifter, which is a few screws and pins.
You'll want a 2000+ cluster if you can help it. Earlier model clusters cause air bag lights to come on, I have this issue, but I ignore it since it doesn't effect anything. I just blocked out the airbag light.
