Where can I find parts? Are there plastic equivalent I can buy? Thanks.

There are inexpensive replacements mostly made of plastic that will fit
the vast majority of tanks. There are fill kits that completely replace
that part, replacement flappers, and even handle levers. A whole fill kit
costs under $10.
