WTB Alfa Q2 diff to suit a alfa GT 3.2 6 speed Manual

[marinoci]

I just took possession of a Alfa Gt 3.2 6 speed and in need of a Diff repair.
Does anyone have a suitable Q2 diff or 6 speed gearbox with Q2 diff available?

cheers,
Marinio

Also considering a 6 speed manual gearbox to replace the potentially  damaged one I have.
