I just completed the restoration of the brake clips for my 1969 RS Z/28 Project. My research lead me to a few, incomplete threads on CRG so I thought I would contribute a comprehensive reference thread in case others can benefit from this information in future. All clips shown are original and restored, none are reproduction. All bolts are manganese phosphated and as there are several threads on CRG that discuss where to source phosphating solution and how to convert fasteners I won't address that process.The black chromate fasteners (3 - double hoop style) are first clear (silver) zinc plated followed by a black chromate immersion solution. The result is similar to low-gloss black paint however more durable and it doesn't flake or chip. The finish is also similar to Black Oxide immersion solution (which does not require zinc plating) and both are available from electroplating suppliers like Caswell. For the semi-transparent blue and green clips I used Steel F/X metal solvent dye. Its best to apply it with a low pressure air brush. It dries quickly and produces a fairly durable flat sheen finish. I applied two light coats. I've include a color coded (by clip) reference from the AIM as well as photos I took at MCACN of some original cars with undisturbed clips to show the location and orientation of each clip.

For the sake of completeness, below are the restored and fasteners (differential brake hose connection to master cylinder - rear to front) and proportioning valve.

God those are beautiful clips Lloyd.
What finish did you use on the one below the mastercylinder?
The "gang clamp"

I believe I left it natural steel however now I believe it may have been zinc plated originally.

James, thanks for your comments. I'm not convinced if the clamp ("gang clamp") was natural steel or plated. None I've seen have been pristine enough to make a good determination. I opted to electroplate mine silver cad which could pass for either.
