Can anyone help to clarify what should be on a January Dearborn S Code valve cover and water pump and then where best to source (or how to make)?
The OK stamp (though there are at least 5 different variations that I've seen on different years - different engine plants) is pretty standard by 68 on many engines
The water pump pulley stamp was only used on some pulleys IMHO likely due to a different supplier, that did not get the engineering number stamped into the metal. Only seen a few cars with these
Don't know where you would purchase them and (just for me) I tend to find that many lack the correct sizing, font, spacing ... that I'm looking for so I spend many hours in Paintbrush and Photoshop redrawing my own (did computer based graphic arts and layout for a fair number of years
