Ofna Solid Center Drive (#33020) - Will it replace any center-diff?

[Chadworkz]

I am building a 1/8 BL buggy and truggy, and want to replace the center-diffs with a solid shaft, and was wondering if [this] is what I need?

It looks like it will work fine, but the ends of the shaft where the drive-cups go look extremely small, so I need verification from you guys to make sure it will work before I buy a couple.

Also, do you think it will be strong enough for a CC/Neu 2200kV on 6S?

Here's the picture...
