Thanks for responding and calling me out; we have had SO many bots with just 1 post I've started testing....I've modified my first post.
I suppose that original Toyota parts might be fairly expensive...
As far as aftermarket parts I would check the popular auto parts store websites. Popular stores here in the US are O'Reilly, Autozone, Advance Auto Parts, and NAPA.
I had a quick look at performance sites, these may have what you're looking for, or they may not. I did not do an in-depth search:

https://www.tunersdepot.com/toyota-p...s-accessories/
Good luck finding the right parts!
