John,
First off, go to the old time locksmith in your town, not Home Depot ;-)
tell him door locks are fiat, circa 1970 and ignition is '70-72 Ford Capri. He probably will just go to the back room and grab them.
but failing that...from my keys
ignition = Taylor X20 or a DL key has multiple numbers on it - X20,FC2, and KL6
locks = ilco FT38, F79-3 or Taylor F79-3
Duplicates are much cheaper than calling a AAA locksmith :-)
