Hi to all who responded so far. Maybe I should have been clearer. The plate that mounts my blower (defroster motor) is a similar but different plate, which I also have. That plate has a depressed shape with the large hole through it (for the air to be drawn through) offset to one side of the speaker outline. The plate I was talking about is completely flat with the same size hole directly in the middle. At first I thought it was home made because it was bent and rusty but it is actually stamped out, not cut out. Its screw holes don't line up with the defroster motor (which uses three screw holes on a larger diameter). It has two pairs of holes, one offset at an angle from the other, possibly for two mounting options for whatever attaches to it. Maybe earlier model's with rear aircon used these? I can't send a picture on this server. If someone has another suggestion, I'll send a photo directly to confirm. Does anyone with an original 300C have nothing under unused speaker holes? Note that I have obtained two speaker grills, one to cover the defroster inlet and the other for the single rear speaker.

My F has that but I'm not home to take a closer look at it. How about a link to a picture??
