I am trying to determine the best course of action to repair my 1965 Gibson LGO / LG0 guitar. The plastic bridge is cracking and I want to keep it as original as possible. It’s in good condition otherwise, since I hardly used it and would start playing it 50+ years later. Is there a part interchange catalog for other models at that time that used these plastic bridges. I occasionally see some on eBay and other sources, and buying one from them. Is there any old stock or replicas made that someone could recommend, or custom made duplicates. I want it to fit the present holes and cover the spot it will be removed from. I appreciate any help. Thank you.
