I see that the srw axle is around 5" narrower than the drw. so if going from 2500 srw converting to drw can you keep the srw axle, just add fenders, tires and wheels. that way you can run 12.50's and keep the tires from sticking out to much. Only problem i can think of is the dually wheels might put the tires to close to the suspension or wheel wells. As far as the front you just need spacers right? thanks
