The Dodge Challenger Message Board

Does anyone know of a source for getting the two dash speaker grilles (not the center one)? I have a dash cap that had the 3-speaker setup and I want to utilize the grilles but cannot seem to find anyone that offers them.
I'm planning on installing a new cap over this old dash, but will need the grilles to complete the install.

Ebay?

Be aware that they are marked left & right. The also have a B for Barracuda & a J for Challenger. They have different profiles from model to model.
