Pulley dates,how to read?
Missing waterpump pulley for my 69 RS, Gm number 3932402 DU. Currently there are 2 on ebay one is dated 19 0 and the other 37 9.Im realize the last number is the year but are the first 2 numbers the month and day or day of the year? My engine has a assembly date of 12 12 so i realize these two wont be correct but i need to know how to read them correctly for future reference. Thanks in advance
