I have a good 1" difference. I'm going to install 3/8" block, i know it is not enought to level it but since i have the heavy OME kit installed and basicly only drove 50 miles i can understand the right side so high since there hasn't been any real weight on the right side to break in the spring. ARB told me to drive 1000km, then mesure again the lean should have drop from 1" to at least half of it. Being a LHD with spare on the right obviously going to lean to the left no mather what.
When i got the cruiser down the lift after the OME installation i only had 1/4" difference side to side. So the left side did settle and mostlikely not the right side.

Too much to do...
Think about where the gas tank is. That is a lot of weight on the right side. Also, when the driver sits in the vehicle, the, original design may have been to counter that as well, but the gas tank and spare tire carrier (1974 and earlier) on the right side definitely put a lot of weight on it. Driveline torque would only be applicable when under acceleration, for under engine compression braking it would reverse the effect. Well, that's my 2 cents. 
Hmmm, it seems to me that you are a little too ashamed.... You see, when you let the fat girl ride in front and be proud of her, the Toy will ride nice and even and you'll have a happy ride, and only get laughed at by a few inconsiderate fella's with hot thin girlfriends... But putting her behind the drivers seat is awful of you and will cause spring sag...

My tank is under the body in the center and my spare is on the left, aren't the US version of the FJ spare on the left?

My cruiser has slightly slanted to the right from the day I got it. It was three years old. Over the years it has gotten more noticeable so
I put some new springs on to no avail so I made one shackle a bit longer and that didn't work either.
The slant is about a half inch lower but has never caused any problem so I have just lived with it.
I have slightly jacked up the right front corner bringing the left rear down and the back looks level.
I never thought a spacer on the axle so I might try it some time.
Many years ago there was a guy in our neighborhood that was at least 300 pounds if not more.
He had a 62 GMC pick up that he took in for a front end alignment.
After a couple failed alignments some bright guy decided to do the alignment with Buddha in the truck and it worked.
