If you’ve got a 1967 Mustang, it's likely that you’ve seen parts catalogs make a distinction between early and late production models. Several things about the 1967 Mustang changed during the course of the year. In this video, I’ll show you the parts that are different, and how to spot those differences.
Some background:
The notion that there is only two variations of the 1967 Mustang, early and late production, is incorrect. The reality is: Ford phased out parts at different times during the production year, and each of the 3 Ford plants had their own schedule. For example, the early San Jose cars all had solid shaft steering columns (except tilt-away optioned ones), not all late San Jose cars had rag joints.
In general, early 1967 Mustangs were built from August 1966 - December 1966, and late model is January to July. You can find the door tag with your build date on the edge of the drivers door.
