Ok here is the picture of the diff:


And the flange that is on the right hand side.

Now i havent measured it, so how du you measure these?

And also it seems like the splined shaft must be smaler on the left (xshaft) side of the diff, as i couldnt fit this flange on that side as it was to big.


But i prolly need a grp a sump then, and modify the group a driveshaft if its not smarter to go for group a hubs at the same time.
