Cigarette lighter

I can not figure out how to attach the cigarette lighter to the dash. I may be missing a piece.

Here is what I have, I am calling the thing on the left the lighter and the thing on the right a socket.

The lighter fits into the socket and the socket fits into a hole near the ashtrasy.


My problem is there is nothing holding the socket in the hole. I am missing a retainer so I bought a new socket and retainer from California Mustang.
