I am trying to replace
Suzuki does sell individual replacements, I bought a few last year. If there are a few unusable chimes now, you can try to tune them, nothing to lose, I was able to tune 8 of ours and 2 others were too far gone and had to be replaced. They tune like a tuning fork, which is what they are. If the chime is flat, you either file the tips, in effect making the legs shorter, this must be done evenly or sustain will be affected, or, the inside of the legs near the tips can be filed, again evenly, to reduce mass. If the chime is sharp, filing is done down in the "******" area.
