Question about wheel color on 67 - 68's.

[67_C-30]

I've looked at lot of original trucks, and original ads, and there seems to be no rhyme or reason on wheel color. I see trucks of all colors with black rims, white rims, silver rims, and sometimes body colored rims. Is there any determination based on packages, or was it just random?

67-68 K20's were equipped with black painted lock ring wheels which had no bright trim or caps.
67-68 K10's typically came with silver color wheels and painted caps.

69 on up 20 series black lock ring wheels faded away slowly, and went to all white one piece steel wheels with bright caps.
