Welcome to the forum!
Several original component finishes:
-fan...it would depend on which original fan. the base 400 4 blade fan was typically painted a 60 % gloss black. the factory 5 blade flex fan has no paint on the stainless blades, they will be an amber color after 50 years.
-the multi piece damper (balancer) is painted '66-70 Pontiac blue, many top restorers use a gray black phosphate to plate the stamped steel inset ring, & the 6 bolts get a black or gray/black phosphate finish.
-engine pulleys are 90% gloss black
-engine stamped steel brackets are 60% gloss black, the alum pivot block for power steering is natural aluminum
-stamped steel spark plug retainers are clear cad, or silver zinc with a black plastidip finish on the wire retainer section
One of the best ways to note original component finishes is to join one of the national clubs, either GTOAA or POCI, attend a national show, & observe the totally original, as well as Concours restored cars. Understanding the judging systems used by both organizations, GTOAA has a much better researched & more stringent Concours judging system in place for '64-73 Pontiac A-body's.
