I need the cast iron single groove power steering pump pulley for a 1967 L79 327 with no other pertinent options. The assembly manual and the GM parts book show this pulley having part number 3834720. However, some pulleys being sold for this application and claiming to be NOS have the number "3834270 GM" appearing as a white paint notation on the back side of the pulley.
Can someone explain why the advertised NOS pulley displays the number 3834270 and not the correct part number 3834720? Does this discrepancy indicate an inferior reproduction?
Thanks for your assistance.
