I use to be able to do this, but I cant anymore. You are going to have to call a dealer. You do have an 2004. All the Sportsman 500's in that year where 4x4.
If you give then VIN to a dealer, they will be able to tell you your A04CH50AA number...a hint, the last two letters "AA" "AC" etc, are color codes for plastics and decals and do not play a factor in what parts you need in non-color related. There really are not as many models as you think, and 95% of the parts are the exact same from model to model in that year.
But the only way to get the model # is to call the dealer and ask for it. Again, I wish I could help. 3 weeks ago I could have.
