I have a 6/70 that I am restoring.  The sway bar brackets that bolt to the bottom of the frame rails and hold the sway bar bushings seem to be the exact shape as my 5/71 in every way.  Except on my 6/70 they were never painted.  They appear as if they were yellow zinc.  My car has been sitting for a very long time so I dont think the suspension components have been modified.

I like the look of properly zinc'd parts but I am not a big fan when it is over done.

Has anyone ever seen these brackets zinc from the factory or have you only seen black?  

None of my Zs are zinc (see signature for my Zs).
