well lazy doesn't get results so I went and measured with calipers... looks to be 9.75mm (.384")... which is closest to 3/8" ... So I'm gonna order some of these

Or maybe just run to Lowes and see if they have something that fits (in a color that works).
That's weird, 3/8" worked perfect in mine...
I took some pics of packaging and paint and install on truck - will post later when I have time...
Waiting on grey ones from Amazon to see if the color matches.
I've tried a couple plugs... the ones from Amazon linked above - fit but the color is a little too light (for me)... this would be a good option for anyone that wants a hassle-free decent way to plug the hole...
The ones I'm using now are from Lowes (see first pic for part #) - they are white, and fit perfect (flush and secure) - I painted them with some spray paint I had on hand (it's a little too dark, but looks like rivets in the bumper/skid plate)... I used two quick wet coats just to see what it looked like... I'll get another set and prep them better with adhesion promoter and multiple light coats (that way there's a better chance of longevity).
I haven't washed the truck or anything else to test the paint adhesion - but have been driving (paved roads around dirt fields as well as freeway) all week - they are holding up.
Kind of a long post for such a simple subject - but those plate holes bug me (as they do others here) so I thought this might help others too... The Amazon plugs are pigmented grey (more like dull silver) so no worry about chipping or fading - for anyone that might choose those... I might use them eventually - if the painted ones don't hold up.
The last pic shows the Amazon plug (upper left) compared to the painted Lowes plugs.
Sorry for the crappy pics - I had to stand at an angle so my shadow didn't block view of the plugs.
