I have the snorkel off of my 72 351C 2V with an engine build date of November 71. Their is a part number stamp on the bottom of the snorkel that I am getting a rubber stamp made of. The number is mostly there accept the last two characters. What is legible reads D2AF-9D626-??, the first unknown character may be a C and possibly an A after that as only the bottom 1/8 of the left leg of what could be an A is legible. Any guidance on what the last two characters would be? In looking through some of my books for the correct part number they reference D4 numbers, which I assume are service part numbers.
Thank you,
Brian
