I am looking for a set of Ness Fly Bars that fit a 04 Vegas. I found a set part# 2875165 but they are not on the fitment chart on Pure Polaris. Why is it that 04 bars will fit 05,06,07...etc but 05,06,07...etc bars won't fit the 04? And I don't have to have the Fly bars maybe another brand, I just like the t-bar style. Any suggestions?
