You could try Traxxion Dynamics but I think it's $$$$
I'd want to see them and find out what they mean by banged up too. Since they're inverted forks, I don't see how salt water damage is possible.Did you get to see the “banged up” tubes? You would think they could at least show you what they are talking about. Just my opinion. But I’d just go with what you’ve done and see what shakes out. Chances are you’ll get good miles out of it before anything leaks again. It is a gamble but I’d have done the same thing you did. Stay safe.
