Interchangeable Rear End

[Lextreme II]

From what JBrady stated:
According to the various posted sources the following ratios are:

1993-1998 Supra TT manual - 3.133 (torsen)
1998+ Lexus V8 Cars VVTi - 3.266 (open differential only)
1990-1997 LS400 - 3.62 (open differential only)
1993-1996 Supra TT auto - 3.769 (torsen, 3.77 not the usual 3.76 quoted)
1997-1998 Supra TT auto - 3.769 (open standard, torsen available)

1992-1997 Lexus SC400 - 3.912 (open differential only)

1992-1998 Lexus SC300 manual - 4.08 (open differential only)
1997-1998 Supra non turbo - 4.08 (open standard, limited slip available)
1992-2000 Lexus SC300 automatic - 4.272 (open differential only)
1993-1996 Supra non turbo - 4.272 (open standard, limited slip available)

I wonder if it is possible to install the SC300 rear end gear into my LS400
