question about the “appearance” of factory 68 disc brake components.

I'm putting 73 discs on my 68, but I'm interested in making it look correct at least so far as color on the different pieces...spindles, calipers, caliper mounts, and for that matter, upper and lower control arms and lower ball joint/steering arms, even though its 73 stuff on a 68. Were these pieces black or natural or something else? Thanks for any help. Ken.
