Need some info.
I'm looking for the following gear oils for a nissan D21, 4x4 pickup:
1) 75w90 or 80w90 GL4 for the transmission
2) 75w90 or 80w90 GL5 for the front and rear differentials
3) ATF dexron 3 for the transfer case and psf

Preferably a known, quality brand oil available in Liter packing. Any idea if Caltex or Castrol carry these oils?

Also, does anyone know if the D21 series, 4x4 pickup uses a LSD?
