To 70-74 Dodge Challenger Fans...Armrest Question?
 

Hi guys, this might sound stupid, but I'm trying to figure out what goes in the door panel, where the armrest is?

Would anybody know what goes in there? And where I can find this part, or for that matter what it's called.

Originally when I bought the car, there were no door panels, so I'm kind of lost what goes there.

Thanks

A PLAStic insert/cup goes there

Any idea where I might buy it?

thanks
