yes. Simple swap, but if you ride hard I would not recommend it. The new post is heavy & weak. It will end then snap if you ride hard.
SO, that said, to do it, it's a simple swap over, but you've got totally different bars than we do, so you'll be way up in the air, too high for stock cables. To do it right, I'd get an 07+ set of bars (countrycat usually has some, also Michelle at oregon trail sports can get them for you) and swap over your controls.
