Sheet Metal Parts Location Unknown

Can anyone tell me where these sheet metal parts go on my XK140 DHC? I took a lot of pictures but these parts are not there.

Thanks in advance.

I have neither a 140 nor a DHC, but because they are tapered, perhaps inside the door or in the well behind the seats.

I have seen most if not all parts of all XK’s 120-150 and never seen these before
