What carburetor do I have?

I recently bought a 73 d100 with a 318.i want to do a rebuild but I cannot tell whether I have a 2b carb that is Carter or Holley because the auto parts store I am looking for a carb rebuild kit.
How can I tell which one I have?

The pictured carburetor is a Holley 2280. The 2280 was introduced in 1978 on 318 Electronic Lean Burn (ELB) applications. It was used through 1987 in various 318 applications, both ELB (or Electronic Spark Advance, ESA), and non-ELB/ESA applications. The later electronic feedback version of the 2280 is the 6280.

The Holley list number to identify the carburetor further is located as shown in the following:

A 1973 D100 318 was originally equipped with a Carter BBD 1-1/4 carburetor. The 2280 can bolt on in place of the Carter as well as a Rochester 2GC.

NOTE: The referenced Carter "High Top BBD" was possibly referencing this version:
