Finally got the Sheldon nuts and have the fenders where I want. Front fender was a lot easier than the rear. The bracket for the rear caliper isn't as good as the front. I might fabricate a bracket like the fronts and rivet to the fender to improve fitment at the rear brake. Otherwise I'm happy with how the fenders look. Huge pain to get the position correct and I probably won't ever do this again 😂
