Hola Luis, hi cherisheyes,
4 bolt neck plates were used on 3 models of Silverstar only
Spagetti logo ( to 1983) = SS60 - pickups grey with 'U' stamp
Script logo (84-88) = TSS60 + TSS80 - not sure about pickups as no-one has recorded a TSS-60 or 80 to date.
Spagetti logo SS-80 had DiMarzio pups with flat poles, not the 'E' type that had staggered poles.
For the record, the Silverstar SS60 had the logo colour same as ST style - tan with black liner whereas the regular Silverstar have Black logo with silver liner.
regards
Peter Mac
