I mounted my Gilles Berthoud fenders with standard Berthoud stays, Tubus rear rack mount and SKS mounts on the rear and on the front standard Berthoud stays and fork crown mount and the addition of standard bolt fixing for a Velo Orange Pass Hunter front rack.





The Velo Orange rack mounting point can be seen in the lower pic with the blue framed bike with mounted khaki bag:
VO Pass Hunter Front Rack - Racks - Racks & Decaleurs - Accessories

The only rattling came from the front fender and was eliminated when I added the front VO rack which holds the front of the fender in position.

Be aware my bike has suspension corrected front forks resulting in my having to cut and weld in a different position the fork crown stay of the rack to make it fit.
Not a cheap proposition if like me you don't know any stainless welders locally.
