I have been thinking of refinishing the suspension on my 1982 BB512i. The control arms on mine appear to be silver cad with some gold cad hardware . However, when I dropped by TRutlands this morning to look at some new ones, the control arms there were gold cad, although some used ones they had were silver cad. As always, it is possible with Ferrari that they were gold cad plated one year and silver cad plated the next. Does any one have a definitive answer as to whether the control arms on a Boxer in 1982 were gold cad or silver cad? Any info will be appreciated.
