Default Kaaz lsd uzz40 dat3020?

I came across this LSD Differential, it says compatible with UZZ40

APPLICATION 6:
Make - Lexus
Model - Soarer
Series - UZZ40
Year - August 1996 - April 2003


SC430 Chassis is UZZ40
Does anyone know if this will fit in SC430 Pumpkin?

An update for this
I e-mailed Kaaz about their LSD if it will fit SC430 and this is their respond:
Hi,

Thank you for your inquiry.
The part number DAT3020 will only fit the UZZ40 until about April '03 production.
Sometime in 2003, Toyota made a change in the rear differential casing
design. The older unit had a cutout on the casing to allow our lsd to fit.
The newer casing does not have this cutout so our unit will not fit.
I don't think the newer SC430 have this cutout.

Please see the attached photo showing the cutout and not cutout.
The only way to fit our unit to the newer vehicle will be to swap out
the rear differential casing to the older style.


Best Regards,
Ray Nakadate
Kaaz USA
Also Kaaz attached two photos for explaning:
First photo no cut out from 2004 - 2010.
Second photo with the cut out for 2002 - 2003, The ones will fit.

So the only way to fit Kaaz LSD 2 way by buying 2002 or 2003 pumpkin.

You can use the 98-2000 LS400 , JDM MKIV 6speed TT pumpkins too .. they will have same 3.26 gear ratio and bolt in to the SC430 subframe.

Not all Soarer pumpkins will have same 3.26 gear ratio as that of our SC430 .

Thank you for the input but LS400 1995-2000 "Chassis code UCF20" does not support Kaaz LSD, so even if it fits you can't install Kaaz LSD.

SC300 and SC400 both fit Kaaz LSD, ratio 4.11 - 3.91, but i don't know if they can fit in SC430.

According to this thread, it seems 2002 is only one that different from the rest "2003-2005".
To narrow it down to 2003 i guess.
