Cargo lamp parts

[DuckAholic1]

Hey Everyone! So, today I purchased a new to me cargo lamp from the local Pick n pull. When I removed it from the truck, I could not remove the rubber gasket/rubber oring things in which the screws screw into, without them breaking off, which they did. (Sorry for the strange way I'm explaining it,Not sure what there called exactly!) My question is this: What is the proper name of these, & where can I find them?? Does anyone know what I am referring to?? Sure hope so, cause I'm confused also!!!! Thanks much in advance!!!
