If you want to get it up and running because of carb issues the # you are using wont really help the parts guy much. You need the # on the triangular ID tag, or tell them you need a kit for the Holley 1904. This carb was used on various Internationals from the 50's to 70's and chrysler slant 6's from 60 to about 70. I rebuild one of these carbs every year or so and always find the kits in stock at my local Motion auto parts store or Napa. This little carb is simple to fix and tune. I also agree that the later manifold and 2 barrel carb is an upgrade in performance, but I have both and really dont think its all that big of an improvement.
