First 'where can I order that part from' query

Just started driving my new to me Tacoma around this week, and I'd like to get an idea where to source interior parts. I need to replace the missing plastic handle that covers the 'seat fold down' lever on the front passenger bucket seat. Elder kid will be riding with me sometimes and using the extended cab drop seat, so I want the front seat easy and comfortable to fold down.

Am I gonna have to go the junk yard route, or can parts like that lever cover be sourced new?

Thanks!
