Ok, fingers crossed this 2001 sc430 diff has compatible axle stubs so I don't have to pay extra in labor for the shop to swab stubs. Only reason i'm concerned is because of this video because his gs430 diff needed to have the axle stubs swapped over, regardless i'm getting a fairly good deal and i'm gonna bring a friend to make a day trip out of it!!!

Correction to my earlier post: the 2001-2003 LS430 and GS430 diffs have the axle stub side type designs. Not 2004 and later versions.

And of course the 2001-2010 SC430's (and their Z40 Soarer counterparts in Japan) all used the same older side axle stub design.

After those model years Lexus switched to non axle stub modified versions of this diff design which we CANNOT use.

....

The SC430's should have compatible axle stubs for our cars since it is a common thing for later model year SC430 owners to swap in Supra MKIV TT Automatic 3.769:1 Torsen LSD diffs into their cars to get an upgrade from their factory open diffs. I haven't heard of issues with those cars cross swapping with MKIV diffs.

You will most likely need to swap on an SC300/400/Soarer(Z30) companion flange however. Don't impact it on-- follow the SC300/400 or Supra MKIV TSRM for proper reinstallation procedure of that part with a proper torque wrench. I believe the official way calls for a dial torque wrench specifically.

.....

Either way you will at least be working with a diff version that CAN have all the correct parts fitted. You cannot do this with the later 200mm Lexus diffs which have no provision for built-in side axle stubs at all since in those designs the splines are expected inserted and are part of the drive axles themselves.
