>From the picture, the two-barrel motorcraft (2100) carb, was made on October 6 1972 or November 6, 1972 (depending on whether you ignore the I in the date sequence). It was made for a 1973 model car with an R code (according to the Motorcraft codes, which I don't know) engine and an "A" transmission. The Holley carbs should have a List number on the front side of the air horn which you can use to better identify the carbs.
