Cupholder / spring

[Mattski]

After a bored morning, I've (gently) pried open a flap on the passenger side lower dash, above the power socket, to discover a cupholder!

 

After taking all the lower dash trim off, it looks like the screw that holds the cupholder return spring is missing. Does anyone have one?

Here's a pic from another site that I googled:

Failing that, I guess it'll mean a new cupholder...
