Seat Belt strap Holders What Application are these?

Bought these on Ebay recently. Seller said they were correct for 70-75 A body Dusters.

Are they correct for anny other year or model Mopar?

Specificly for my 69 Coronet? Or just A-bodies.

Thanks

Beuller...beuller...anyone?

Many Thanks for the numerous responses.

Very helpful.

Never seen a car part like that.
Looks like an appliance part.

no idea what that is.

1969 cars use the plastic belt receiver for the buckle end to be stored that screws to the front upper part of the vertical portion of the seats.
I don't have a picture of it but certainly someone here does.
