Hi Patrick.
It's never a one-size-fits-all approach.
Make sure to have a discussion with your customer so you understand what they expect from the piano and they understand the condition and limitations of the piano.
Check to see if there are plastic damper or hammer flanges that will need to be replaced as well. If the piano has plastic flanges, even if they haven't broken yet, I would suggest replacing them as well.
As long as the customer is given the information, prices and honest assessment and expectations regarding the condition, thay can decide for themselves what they want to do.
I am currently working on a spinet: replacing elbows and damper flanges. The owner wants to keep this piano alive as it was his dad's piano. He understands that the piano has limitations and will only be good as a starter piano but that's all he wants plus that it has a lot of sentimental value for him.
Most times, people won't spend that money to keep it going but rather buy a better used piano but they need the info to be able to come to a conclusion that'll work for them.
