I assume your talking about the snake? They are all the same. Your gonna need a torx screwdriver to get the pony emblem out and to screw in the new snake one.
You can buy them on ebay for like $20-25, or you can try your local dealership. I was quoted $40 from them so I bought mine off ebay.
As far as the torx bits/drivers, you can get them at places like home depot, sears, most local hardware stores, etc.
