Do it yourself. I added a couple to my Champ. I actually prefer the rod holders just fastened to the gunnel. The rod holders adapters can break before they get tight enough to secure the holder and keep it from spinning. I just ordered the rails and parts on line. I added some to my Ranger too when I had it.
