Outer Limits 4x4 Board

i need to know how wide a hilux 106 front diff is when it has IFS front hubs fitted also
is the spring spacing the same as earlier hilux's?
if anyone can point me in the right direction it would be very handy.

WMS to WMS is 1473mm

now i just need to know about spring spacing differences between a 106 and earlier models.
the info is needed as i am putting together an application to get approval for a sas on a vitara.
