1970 B Body rear speaker

Any one have a photo and part number for a correct rear single speaker for my 70 super bee. And what years will be the same? I have the AM FM radio with the fader switch on the lower dash.

Looks like -

RR Speaker and Control Package (1-87-2)
Speaker and fader control, 1970 Coronet, PN 2947234

Shared with 1970 Chargers.

Any one have a photo of one? And what years are the same? THANKS

Here it is
