100Q Torsen unit and CV flange error ETKA

[Denis]

Hi all , i want to fix my 100Q but the end section  , Torsen unit is broken.

So, i m looking for a Torsen unit for 100Q 1989.

The other question is why ETKA tells the 100Q tranny flanges are 108mm and on mine is 100mm,
And why ETKA tells my 90 flange tranny is 100mm, and mine is 108mm !!!! as on my  5000TQ 1987.

Thanks
