Help Identifying Part

I am trying to install my 3rd brake light from MESO and ran into a few issues that I’ve sorted out but one of the nylon nuts that is used to hold the brake light to cab broke. And the other one does not look much better so I would like to replace both of them. Does anyone know the Part number for these? I looked online but could not seem to find them other than the entire 3rd brake light assembly. The picture shown is not of my truck but they are the one circled in red and for a 2015

thanks in advance

 

I’m not 100% sure.
But I believe this is it.
