Auto-Lite/Motorcraft 2100 series 2V. This is the 1962/69 type. 1970/74 type has a choke pull-off diaphragm mounted on the air horn (top of the carb).

If you need a carb kit: D4AZ-9A586-A (replaced C2AZ-9A586-B) .. Auto-Lite/Motorcraft 2100 series 2V Carburetor Kit (Motorcraft CT-499-D) / Available from Ford & auto parts stores.

1962/74 Trucks/Passenger Cars; 1966/74 Bronco; 1969/74 Econoline.

At the side of the carb (as partly visible in the left picture) You'll find
the size of the venturi (for example 1.14 or 1.04 ...). If You're looking
for a replacment of the carb, make sure, the new one has the same
venturi.

On the side of the left front mounting flange, right by the bolt, there will be a code stamped. Something like C4AE-B, or 4AE-B, or something similar. If you can post that, then the carb can be identified.
