Sway bar brackets - correct application and color?

[Dave69x33]

In Jerry MacNeish's book, The Definitive 1969 Camaro Z/28-SS396 Fact Book, he noted that in February 1969, new sway bar brackets went into production.  These new brackets had four "fingers" to better retain the bushings.  See attached pic.  My 69 is a May build car.

Can anyone confirm how long the original brackets were used on their 69's, or about how long past February the original brackets were used?  Providing your VIN # or build date will be helpful.

Also, Jerry notes the brackets are to be 60 percent gloss black.  Were they painted or dark gray/black phosphate and oiled which appears to be about the same color sheen?  Where any of these brackets zinc or silver cadium plated.

Where bolts gray phosphate or silver cad?

Thanks for you help.

My original 02D Norwood car has the "old" brackets (without the "fingers"), with phosphated bolts. The brackets were dip-primed semi-gloss black.
