64 Lincoln Ash tray assembly won't close

I have a 1964 Lincoln Continental. The Dash, ash tray assembly is a big one, and its open now but wont stay shut when you push it in. Something is missing to keep it shut. Anyone have one and can tell me what to add to it. They is only the hinge at the bottom and that is it.

mine is doing the same thing I heard there is a spring that pulls it closed. Let me know if you find out for sure.

There is a spring on the passenger side of the unit. It is a round spring with a left and a right bend on the ends that fit into holes - one on the ash tray and one on the dashboard. If the unit was removed it falls out. Try removing the unit and check on the top of the mounting rail it may still be sitting there stuck on the insulation.
