Any Motorcraft 2100 or 2150 carb will fit if it uses the standard 2-bbl mounting flange (as would a Holley 2300) or if it has the smaller flange it will either need a Holley, Motorcraft, or Weber 5200 (all variants of the same carburetor design, found frequently on Fords, Volkswagens, and Toyotas) or an adapter plate from Mr. Gasket and the 2-bbl. of your choice.
When it comes to distributors, if you want to go with points, use a '74 distributor with single vacuum advance for simplicity or if you want electronic ignition, use a '75-79 distributor, ignition module, and wiring harness.
