Here is the post i found

Caution before ordering guys, I'm pretty sure no gear diff fits without heavy modification.

The X6 gearbox uses the original B4 outdrives. The SC10 B4.1 and B4.2 gear diff mentionned above is wider and doesn't fit. Plus it uses different bearings.

By the way I'd love a gear diff compatible gearbox too. Less wrenching, mo' racing :)

Yep the X6 box is to narrow for a gear diff.

So it's a no go atm...

Yep the link from a past thread says that you need a different hear box....
