The early/late changeover was at approximately SN#18,744 in March 1969. A good rule of thumb is to check the vacuum actuator located on the right side of the firewall. The actuator was changed from the "can" shape on the early 69s to the "double pie plates" shape on the late 69s. This is not always accurate because some of the late 69s have the "can." Many of the parts changed during production, and early and late does not necessarily have anything to do with when the car was built. Even worse, some of the very early 69s used parts leftover from the 68 run, and some of the late 69s have parts that were supposed to be on the 70s.
