I have a full set of these 1977 wheels, 6-lug 15 x 7. They have been painted an argent color with the slots painted black. They look pretty decent, if you zoom in you can see some scuff marks. I never had them balanced but I had no tracking or vibration issues and they seem straight. I don't have center caps or lug nuts.
I will pack them individually in wheel boxes, each box weighing 25 pounds. With shipping costs so pricey I will sell them for only $20 each.
