Zero offset on 14 x 7" rim wheels for P245 60 R14 on stock 1969 Dart, anyone could tell???

I have 14x7 rims on the back of my Scamp but I had rims custom made. I had them take a factory style rallye rim and add all of the added width to the inside. That way it looks stock when looking at the side of the car and the trim ring still fits correctly. I still had to roll the rear inner fender lips so the tires (245/60/14) didn't rub. That was as wide as I could go with the springs still in the stock location. If you do a search on here I think someone had pictures and tire sizes that they used.
