We could also call this thread name that CMP
Pattern 12 Chevrolet based on the following:
- Opening hood makes it a Pattern 12
- Round air in lets one either side of the radiator
- Coolant recovery tank above left front fender
What else can be spotted.
Cheers Phil
PS
Keith those are interesting points about the steering ends, some people like Bart Vanderveen would spot details like this and knew the introduction dates because they had a large collection parts books and would cross reference the before serial number such and such with the production serial number dates which would nail things like the when the Chevy coolant tank moved from the exposed location above the left fender to the more protected spot up under the fender. If I remember correctly the date of the change over from horizontal towing rings to vertical can be nail down the same way.
