How do I take visor apart?

The metal rod pulls out of the visor itself.

To install a new rod, simply push the new rod into the old visor. There is no need to remove the rod from the base unless there is something wrong with either piece.

Thanks, I got that part. Had to install newer bases from the dull ones.
(put on the rod to newer).
It work out great,thanks for the help everyone.
