They should all fit any Valkyrie/any year. However, if your bike has a polished rear drive (Im thinking that was year 2000) but if its polished, the IS one wont be, it will be painted.
Thanks for the info.
I have no way to tell if my rear drive was polished or not, the previous owner had a lot of stuff chrome plated probably back in '99 and either it was a crappy job or since the bike was stored in a shop, covered with a tarp for 2 1/2 - 3 yrs and nothing done to it, even cleaning, the plating is blistering/peeling real bad. So even if it's the factory paint it will be a tremendous improvement.
I bought this thing a few weeks ago and have been looking in the classifieds here and on ebay for items I need. (I'm the one who posted earlier in the week about winning a bid, paid for it immediatly and not receiving the item yet, been almost 2 weeks and still haven't got it)
