Help finding reel parts

So, in this photo, everyone can clearly see my three main in my bass lineup: my SLX 150A 💪, my Metanium 100HG👸🏻, and my Daiwa Regal LT1000🪱 that I just purchased tonight.
My SLX 150 was in retirement, sitting on my desk inside of its box for almost a year after an incident on a big river left it destroyed. I disassembled it and rebuilt it, but I lost two parts in the process: the drag clicker pin and the handle spring.

I looked on Shimano’s website, and they’ve been sold out for about a year, but I want to return my SLX to my lineup. Any websites where I can get them? Can anyone help me find a website that sells them?

Most of this post was just a gear show-off, BTW. Sorry, my bad. 😭 ignore the SUPERIOR last gen nasci c5000xg that’s for my surf.
