Often the frames of the rocker switches are broken. They are identical with the switch frames used in the Fiat 124 Sport or Fiat Dino 2,4. Reproductions are available in the meanwhile, in chrome, black or brown. Obtainable from various suppliers of Fiat classic car parts. Attention: the switches fit into the frame in one orientation only. The actual switches can be reconditioned as long as nothing melted, since they can be dissassembled. If doing so, observe that the rockers can be assembled in one orientation only as well.
