Do you have the deluxe panel that continues over to the glove box panel or the radio plate that does not have a glove box panel??
Anyways, just make your own from plastic sheet that has grain on it. Even though the delete panel is molded in, I looks just like a thin sheet was placed over the controls. Like the mold just had that stuck in there. There is a defined edge and the corners are square.
IIRC, that all that ebay seller is doing then having it chromed OR I think PG Classics might be making a new molded piece.
It might take you around two hours to make your own with painting, bondo, and all. And they will not be rechromed.
