Lightweight trem block option '14 Silo Special

Looking to see if there are any light(er)-weight trem blocks available for a ’14 Silhouette Special. Nothing tonally wrong with the guitar (sounds great and well balanced), but is about 7.8lbs. It plays better than my ’03 hardtail, though the weight becomes an issue after a while.

I did a cursory web search and forum search, but did not find anything specific. Appreciate any direction to companies or forum threads that address this.

Thanks and keep healthy.
