Rubber plugs

[kitttransam]

I can’t find anything about the plugs for the rockers. Anybody have part numbers. And does the rear door area have rubber plugs?  Both sides of my truck don’t have them. Looks like there’s  a hole on the inside area of the rocker too. It’s a 2011 Silverado Ltz crew cab.

I don't know the GM number but I know places like NAPA sometimes sell body plugs and plastic fasteners.

 

Also try looking through this site for the size plugs you need.

Try these numbers, they are for a 2011 Silvy. You can see some photos of some of these by doing an eBay search on the part numbers. At least this is a starting point, hope this helps.
