Welcome. Guild specs do vary and people might want to know a year before answering. That said, Guild generally has parts for models that are currently in production although sometimes it appears you have to be an Authorized Repair Shop to get them. But their track record for matching modern parts to instruments that predate 2014 is pretty spotty. There are threads about replacement bridges but my recollection is that no one is making drop in replacements and so people either craft their own or use something that "kinda works". But you will get a more informed opinion eventually.
