I also came across a thread about Paul Woods putting a helical LSD from the Spyder's C56/65 into a S54 so that's possibly a cheaper option for the NA guys rather then shelling out for a Quaife. Just a matter of finding someone willing to part with it hehe
Yep, the Toyota Factory Helical LSD fits like glove :)
My two ZZW30 LSD's, OBX on the left, Toyota Helical on the right.
