: I have a Ford 4000, 3 cyl. diesel, with serial Number C405356. Could someone please identify what year it was manufactured.
: Thank you.
on the right side, bell housing there are groups of numbers,first group should be something like,7A9B,1st digit is year,1st letter is month,2nd number is day,2nd letter is (i think)am or pm but not sure. Letter/numbers on next line model number and last line serial number,all should be stamped to be valid,hope it helps I just went throu this myself.
