‘64 Dart GT - Moving to bigger wheels

The '70 AAR Cuda and TA Challenger came with 15in but different size tires. E's front, G's back, 60 series. Not sure what size that relates to now, BUT It had a slight rake. Me I would go with 15 inch. wheels, with a slight rake from tire size, if you want that. To much rake is hard on your front suspension, I have always been told.
