Hang on....
You've put a complete axle under the vehicle, yes?
The casings are the same, The brake disk & pads are the same, The CV joints & half-shafts are different (24 v's 12 spline)
...... but you said one side is off-set more than the other?
Borked radius arms are unlikely to make half-an-inch of difference.
If you are proud on the drivers site, I would look to the pan-hard rod: it holds the axle to the drivers side of the chassis, and new springs could be making the car stand taller than before.
The only other thought I have is wheels/tyres: what happens if you swap the wheels over [left to right] ?
