Commando valve cover ID

Thanks for the info. Found 3 boxes at this estate sale marked Misc. mopar/dart stuff & took a gamble on them. Would not open boxes prior to sale so I had no idea of content. Got lucky for once. Ended up with a charger 273 air cleaner(from a dart) with original base & some 10" SBP rear brake drums and the valve covers plus some dart trim pieces that can't be salvaged. Already have cleaned up the aircleaner & added a 273 commando sticker. Valve covers need some work but are restorable & the drums are nice. I am having a good week. Thanks again on the valvecover info.
