Not sure what else to call it - it's the black plastic pocket that goes behind the cupholder on the '96-'98 Civics that don't have a separate cassette/CD player.

Anyway, if you have one, let me know. If it's currently in your car, I'll even trade you a factory CD player for it.

 

Nevermind - made my own console insert, so all is well in Civicland.
