howdy Evan,
most carb kits are generic, servicing models 1100 and 1101 alike.
No specific carb number needed; most of the differences are found in parts that are not contained in a rebuild kit anyway, like main jet and power valve shims; or specifications, like venturi diameter, flange bolt circle and air bleed restrictions.
just get a rebuild kit for 1100-1101 autolite carbs. If the autozone counter kid still insists on a number, tell him C5TF - N - A - 5ED. That should work.
Remember to check for warpage after you have cleaned the body and choke horn. The main body, made from cast aluminum, can be milled using sanding paper taped to a thick sheet of glass or an old mirror. The zamac air horn can hardly be repaired.
