A conventional distributor will work. Count the teeth on the flywheel. I'm not sure I have ever seen the type of setup you describe on a civilian engine. Are you sure the starter is 24 volt? The Stromberg WW is a good carburetor. I would remove the governor. If you have a 4 bolt manifold, WW will bolt right on. If it is a 3 bolt, you will need a 3 bolt Holley. Or just disable the governor. It closed the butterfly when a certain velocity of air was reached. Or just leave it. You probably won't bump the governor anyway. Most of them were set around 3400.
