Center diff question

[Jasper]

People,

I am in the final design stage for a revo conversion. I bought an Ofna ultra lx center diff for the conversion. This one:



For the center shafts, I will use the driveshaft assembly from Traxxas. I will modify the driveshafts to the right length. But the axle, will not fit into the center diff.

So now is my question. Wich center diff do I need, for a perfect fit with the traxxas driveshafts? I will use the plastic kyosho spur gear.

Thank you,

Jasper
