Re: Crank Pulley Color
On the early production 1969 cars I have seen phoshate pullys. Later in the year more black. Just my observations. You can usually find evidence on the back side of a pully. Most hack job restorations attempts never even remove such items...BKH

Re: Crank Pulley Color
I think you are correct about early cars. I think it may have been cheaper to paint or they found a different supplier later in the year. That is were Tinnell found the phosphating (backside) [img]/ubbthreads/images/graemlins/flag.gif[/img]

Re: Crank Pulley Color
I personally love this kind of thread...there is not enough accurate exchange of resto info IMHO. I have bought MANGANESE Phosphating chemical (what most would call "Black") to restore my fasteners, shift linkage and other misc brackets. I have also bought ZINC Phosphating material (Grayish more so than Black) to refinish my hood hinges, hood catch, etc..... I have not seen a Phosphated factory crank pulley, but have seen a 458DA Deep Groove smog pulley with Zinc Phosphating. Was the Phosphating on crank pulley the same GRAY as Smog Pulley????? And will ANYBODY be more specific on WHAT (Brand/Name color) they use to replicate 60% semi gloss Thanks, Chuck S / Seattle
