As I understand the post. You have an open drive shaft. The "center" pin on the springs is not in the center(true). So turning the spring front to rear will change the position of the axle in the wheelwell. It will move it to the rear. Will it center in the wheel well? You would have to measure to find out. It will move to the rear. The point I was trying to make, was the hole in the perch saddle that sits over the center pin, can be redrilled and make turning the springs around unnecessary(I am a bit lazy, drill two holes, or turn the spring...). If I got it wrong(happens often) and you still have an enclosed drive shaft(torque tube) then the only way to move the axle back wards is to turn the spring end for end. Drilling a new hole in the cast perch/pivot assembly would be unwise. Will this center the axle in the wheel well? It will move the axle to the rear and that might be the look you are after. Regarding the ring/pinion ratio, the only option I am aware of is the 3.55 option. Other options are available with the open drive shaft. But the torque tube and carrier only ring pinion sets I know of are stock(4.11) and 3.55 from after market providers.
