Where to obtain Thunder rear string retainer bar?

I'm not sure what they're called sorry, but the metal bar which the strings thread through as seen here:



Would anyone know of something available which will fit there? The proprietary original hardware is impossible to find

I am afraid the only way is to get one custom made.
But really, anyone with a pair of right hands, a drill press and a belt sander table can do so from a strip of brass.

I don't think I've ever seen a request for this particular part before.
It's an odd one and I'm wondering how on earth it went missing?!
String locks, truss rod covers and whammy bars, yes. But a string ferrule tone block? Nope.

Unfortunately I don't have any specific information on this part but I do have a Thunder so I know what you're looking for.

I cannot say without measuring mine if it's based on any standard or is a proprietary design. My guess would be the latter and you will not likely find a "drop in" part.

If you haven't done it already, check eBay to see what's available: LINK

The only alternative suggestion I have involves plugging the hole and drilling for individual ferrule inserts like you find on a Telecaster for example. Not ideal, and you lose the tone block benefit, but at least you're up and playing.
