Sitting here reading old threads when you chimed in. Too many variables for me to pick tires and wheels but can't cut a car to make the wheels fit. Too nice of a car. Thanks for your comment though.
I understand, I always figure it's just metal and it can be fixed.
I'm a dart guy so they have the cut quarters on 68 super stock darts, that's really awesome looking to me so I duplicated it on my 70.
I picked a 28 in tall tire for the fronts and a 31 in tall tire for the back, mine however is a drag car project so I don't mind doing the necessary cutting. Those tires need some help to fit lol.
Good luck figuring out the tires you want
