To compliment your illustrations with a j30 vlsd...

btw: changing the shims to thicker or doubled up shims only increase the gear engagement on the internal spider gears ( 4 of them) which may be the blame for a ratcheting rear diff. This noise goes away once you have worn new patterns into the side and spider gears. in other words, Grinds The Metal and increases the friction/grip.

when you take the tolerances out of the factory gear setup, who cares what side the shims go on. should be the same long term result.

it does make a cheap 1.5 at the expense of a long living rear diff...

your choice.

EDIT: this ring gear is from a 240sx 49:12. j30 come with 47:12
