Where do I find the plastic Screw Retainer that holds headlight in place?

Was uninstalling my headlights tonight to send off and lost the plastic retainer where the 10mm screw fastens the plastic tab "arm" to the inner fender....

Where can I find this? Any help would be much appreciated!

 

If there are no auto stores or online stores where to purchase parts specifically try the.....Dealer????.....Junk yard???....Craigslist (parting out a Tacoma)???....

 

I have a few brand new but costs more to mail/ship.
Part is only about $1 at the dealer
Part number
90189-05142

These plastic pieces ten to break when over tightening.
Good luck

 

Thank You all for the reply! I came across a diagram online late last night and @Siblue confirmed it's the same part #. The parts department had no clue what I was referring to, smh. Will be picking this up later today.

Thanks again TW!
