There is a turning stop on the dana 30 front axle that is easily adjusted with a wrench. Look on the inside of the steering knuckle for a bolt that contacts the axle on full lock. Install your lift and tires. If the tires rub, adjust the steering stop until they have no interference. The correct solution would be to then order the rims with less backspacing. If you adjust the steering stop you can be 100% sure if you need new rims or not before you order them.
