Hello !
One of the string points snapped off my tail piece for my 515 and Eastman sent me a replacement tail piece.

I took out the 3 screws from the old one, but the strap button would not come off. I tried using pliers to turn the strap button, but shredded the top of the button in the process.

Any ideas how to get the strap button off so I can remove the tail piece?
Any suggestion on where to get a new strap button?

Thanks for your help
