68 Barracuda Notch 15x7 Wheel Question

I know there is a ton of wheel questions, so sorry for asking another one. I found a set of 15 inch steel wheels that were painted and ordered for a Charger from Classic Industries. They were accidentally ordered with the small bolt pattern and are for sale in my area. Will 15x7 with 4 inch back space work on my notch for the front and the back? My car has drum brakes and stock suspension. Anybody with info. or a notch that can let me know would be much appreciated...Thanks
