'68 shortbed stock steel wheel color?

[x33d80]

Just picked up an unmolested '68 shortbed custom cab with the stock 6 lug steel wheels and was wondering if anyone knows what color the wheels were originally painted? I am very well versed in Camaro lore, and know that steel wheels on camaros and other chevrolets of the time period were painted body color. I was assuming that trucks were too, but after really looking at mine it would appear the wheels are an argent silver like rally wheels. Granted my wheels are somewhat rusty, but they do not appear to be painted saddle fawn and do not look like they have ever been re-painted. I have seen some trucks with the wheels painted the body color, so I was wondering maybe if on certain colors, the wheels were body color and on others they were silver? Going for a stock look with the only mod being an ECE suspension 4 / 6 drop. Thanks!
