I have a 1994 Nitro TF170 with a Trailstar trailer. After surviving several blowouts, I could really use some new fenders. (blowouts are hard on fenders) I've looked everywhere and can't find replacement fenders. They're 9" wide at the bottom where they bolt on and 8" wide top dead center. So a regular straight fender won't work. Called my local Nitro dealer and he said the trailer too old, don't know where to get them. Anyone have any suggestions?
