Hi guys, I want to share the information necessary to install a LSD and/or the 4.3 final drive gear into the C50 transmission. Here is the list of parts needed:

1) Limited Slip Differential of your choice
2) New differential bearings
3) Both axle seals
4) 2004 scion Xb output shaft
5) 2004 scion Xb ring gear
6) Control shaft cover gasket
7) 1 or 2 differential shims

Measurements and inspection info here:
