Plymouth Valiant model car or model kit

Did Chrysler ever produce any "dealer promo" models of a Valiant? I've had Dart Sports & seen several other of the "sportier" models. Was it MPC who produced them? Try contacting some of the remaining model manufacturers? There were some Japanese model companies as well. I have a '72 or '73(?) Challenger model by one but don't recall the company name or where it's stashed at the moment.
