3.27

The 98-00 SC400 used the same 5AT that ran in the GS400. Both used a 3.7 rear end that is compatible with the same LSD units as the 92-97 SC rear ends.

I am presonally putting a TRD LSD onto a 98-00 SC400 rear end with a 3.27 ratio for the 5MT project I have in the works.

If you are in need of one, Gazi (Member name: Aliga) sells them for $300 shipped...which is not a bad deal for something that is in relatively limited supply.
