Most things are interchangeable between the raptors up until the 06 models ofcourse. I'm pretty sure they are the exact same, my friend has on 02, i have an 04 and it's all the same stuff. Can always call ur yamaha dealer to be 100%
Not entirely sure I know what part you're talking about. Have you looked up the part number under an online microfiche for your bike and then compared it to the 05 model to see if the part numbers are the same?
