I had 40,000 miles behind a Windjammer SS on my K3. I do know that the bracket from even a K8 will fit on the K3 as that is what my SS fairing came from. I have 34,000 miles behind the Windjammer IV on my '81 Gold Wing. The Windjammer SS, III, and IV all have the built in turn signals. The Vindicator and Windjammer II, used the original to the bike turn signals on little brackets. IMHO, the SS, III and IV with the built in turn signals make the fairing a little easier to take off and on. BUT, they are still very easy to take off and on as they are. The best fairing mounting bracket, is the Vetter bracket and the wiring harness. I take my Windjammer off when I do the winter wax job, between riding seasons. The fairing has been off the K3 for years now as I use the Gold Wing, when I am going for a long ride.
