Tailgate plastic inserts

Wondering if anyone knows what the part number is for the tailgate insert screw plastic piece that is threaded by chance?

 

What piece are you talking about? - I grabbed this from Amayama

The 90189-06010 is the piece I'm talking about

They are not threaded. The bolt is designed to cut its own threads. I always start the bolt backwards until I can feel it set into the old threads and then screw it in. If you just drive them in each time and cut new threads you eventually chew them up.

Those parts should be easy to source aftermarket. Autozone usually has a little rack of them, or there is always Amazon.
