WTB date coded water pump.
 

I'm looking for a late 1965 date coded water pump for an early 1966 truck motor. I need one that is stamped K ## 5 or L ## 5. The ## would be 1through 31 for the day of the month. I'm not really concerned with the day but I really need the month to be K or L (for Nov. or Dec.). I also need it to have the threaded hole on the top side for the bypass hose. Thanks for any help.
