with the nismo you break it in differently. just read the manual it says 180miles of normal driving then change the fluid. remember nismo is synthetic, kaaz is organic. don't mix them up. your first mistake was drifting.com and yah just place the shims in the same order that they came out in, rarely has anyone required shimming to have the backlash with in reasonable tolerance levels. and since it seems like you might have bought a used lsd. there is no break-in procedure required(if I read your statement correctly)
