Engine Number

[tartan18]

According to the plates on my car (engine compartment and driver's side door frame) it is a 1975. BUT .... the engine number above the oil filter bracket is 132 A1 0316. This seems to indicate that a previous owner might have put in a later model engine. The numbers below the engine number are 0667769.

Any help in deciphering these numbers so I know what my engine's year is would be appreciated. I am going to order a mechanical fuel pump so I need to know which one will be the "right one."

As always, Much thanks ...
