Honestly I wouldn't worry about it. Fenders are a relatively simple mounting piece. Providing the front tire/wheels are the same width (which most larger bikes are) you shouldn't have much trouble making any fender work on any bike. It would most likely just involve drilling new mounting holes and filling in the old ones (simple fiberglass job).
On thing to keep in mind, if the fender you're going to use wraps around the forks you might want to keep in mind the difference in diamter tween standard and USD forks. Still, I'm sure it can be made to work.
