look for a place that rebuilds hydraulic cylinders, they rechrome the rods on those.
they can tell you where to go
rechroming is highly recommended as far as i am concerned, i bought new stanchions for a v7sport , returned them because the chrome was awful
the pair i got as replacement was even worse, turned out all the big guzzi specialistst over here were selling the same ones
so i ended up having the old ones rechromed.
the result is way better than any chrome that came from italy...
