Re: What is the correct 1967 L79 water pump pulley #
Phosphate black finish can be done in phosphate solution with water heated on barbecue grill. May need to wipe with some black dye to get it as dark as GM had it. Kinda charcoal grey. Paint looks like paint and don't have a texture of phosphate. An original being 50 years old has no sheen or satin look to it. Gun oil rub down may give you longer protection and not kill the texture.
