1973 Dart Swinger Owners + 17" Rims

I'm moving forward with my wheel and tire order.

FRONT:
American Racing T70R 17X7, 0 (4") Offset Wheels.
Yokohama S.drive 215/50-17 Tires.
This will maintain the same tire diameter as the 205/70-14 tires currently on the car.

REAR:
American Racing T70R 17X7, 0 (4") Offset Wheels.
Yokohama S.Drive 235/50-17 Tires.
I'll gain 1/2" of ground clearance vs the current 235/60-14 tires currently on the car.

I'm tempted to go w/ 0 (4.5") Offset 8" rims in the rear, but I only have 1/2" between the sidewall and leafs w/ my current 14 inch wheel setup. I'd have to use spacers and more than likely, I still wouldn't have room for a wider tire.

I'll post pics when I get em on the car.
