I don't think there was a Commander engine option in M5 pickups in '47. But things could have been changed. And one of several transmissions could have been used.
A shop manual would be very useful; not only will it help you identify which engine and transmission you actually do have, but of course it will tell you the best way to do the work required.
There are some small, but significant, differences between Studebaker engines and competitive makes, and there are some special things that need attention. Things like crankshaft end play, wrist pin clamp screws, and valve lifters, among others.
You can buy aerosol cans with the correct green paint from several of the Studebaker vendors.
