the only silvia that had a different final drive ratio from ours was the S15 I thought.

A properly working VLSD should be tough to spin the output shafts by hand. After I rebuilt mine, i had a tough time spinning the stub shafts.

The only markings nissan ever put on their diffs were orange stickers saying VLSD. I don't know if that standard was in Japan, but that's what was done over here.

finally, yes the 5 bolt axles will be stronger. The 91+ silvia got a slightly thicker axle than the CA powered 89-90 (which coincidentally has the same bolt pattern on its axles as we do). If you want to save money, go for the 6 bolt output, but if you want to buy some new axles, the J30 uses the same axle with a 5 bolt pattern.
