This is my brothers car with 29/15/15's. Mini tub and rear moved back 1/4 inch. you could move the rear back another 1/2 inch and fit 30 inch tall tires. With the Dana rear it would be very close to the stock fuel tank. With his smaller 325/50/15 MT DR on the same 10x15 wheel 71/2 BS there is lots of room to lower the car.
