I did this to my 99. I'll try and take some pics for you. But basically, I purchased the tank and seat, then started taking apart my sled to see how it would all fit. On that model I had to build a platform to cover the cooling lines that ran on top of the tunnel. If your 2000 is like my 2000, you won't need to do this. The issue with using the tank is that the hoop that holds the steering stem, is too low, the tank will not fit under it. I had to raise it, and flip the steering stem bracket to the opposite side. Because of this, I'm unable to use the stock knee covers (or whatever you call the cowling vent thing that attaches to this hoop). I'm in the process of making some sort of aluminum covers.
