67 Commando PCV Question

I have a 67 barracuda with a commando 273. I was wondering what the stock PCV valve looked like for this year since the valve cover is a push in type. I know the 66 and earlier commando/charger had a stove pipe with a chrome cap PCV and I was just wondering if for 67 the PCV was just a regular black valve or if it was chrome or unique in some way like the earlier models. I have been looking but haven't been able to find any pics of one on a 67 model.
