Which ss spring to use?

Hey guys, on my 74 duster I have moved the springs in 3'' and have 275 60 15. When I launch hard and theres a passenger in the car(yes, its a street toy) my passenger side will squat enough at launch to rub the tire on the inside of the fender. These are old springs and feel like they are wore out a little. I'm not worried about how rough the ride is...it's just a toy and I don't do long trips in it. Looking to get new springs, but rather than have it lean with 002 and 003 springs, I'd rather run either 002 on both sides or 003 on both sides to keep it level. Which spring is going to give me more height? I know the passenger side is taller when sitting, but wondering if is squats more than the driver side, which if that's the case, running 2 drivers side springs might work better. Anyone have any input on this?
