What is best size wheels and tires for 1962 Lancer GT (Cragar S/S)

Well finally getting around to finishing my Lancer. Getting the Engine/Trans (273/904 ) switched over this weekend. Then I want to put some Tires and Rims on it so I can Figure out the paint. But not sure what is best rim/tire combo-offsets. I really like Cragar S/S. My brother says a good old set of Mopar Rally Rims. Will have the same rear with 5x4 bolt pattern. Keeping the engine stock so no issue with rear. Car is all original and will be keeping the /6 and trans for good measure. But need some expertise on wheel/tire size.
