M6 chain ring bolts…

Hey Peeps, I’m putting some time into an old girl and at each turn she’s resistant to change. Today‘s problem solving starts with M6 chain ring bolts (see pic). I need 5 similar, anyone able to help? Peace and love, H

Eureka, it’s fixed. The granny ring bolts are an exact match for the aforementioned hand cut bolts, so I swop them out and we are good to go.
