Well I am sure 1000's of people have already done this but WOW !
After playing around for an hour or two I located where you can download 1000's of SketchUp components and here is the result.
Go here to download tons of free up to date SketchUp components.
These components install in a folder called /@software/SketchUp/Components/ under program files. Then inside SketchUp, open the Component window and on the right hand side click the arrow and add this folder to the favorites. Then they are all there for the picking.
