What is mechanical and physical difference between ecz 9510Y 1272-1 and a ECZ 9510AD 1273-1 carburetors

It could be that 1272-1 is for Fordomatic cars. 1273-1 is for cars equipped with manual transmissions.

There shouldn’t be any differences between ECZ 9510 Y and ECZ 9510 AC carburetors. The ECZ 9510 AC replaces or supersedes the ECZ 9510 Y carburetor and both are for standard and overdrive 312 engines.
