Is this what I need to switch to Simucube 2?

[Harpo]

It seems I will be able to use my Fanatec wheels with Simucube sport, is this what I need?

Simucube 2 Sport (with Fanatec Quick Release and Adaptor)
Wheel Base Side Fanatec Conversion Kit

If so, the Conversion kit comes in two versions (threaded and non-threaded). The descriptions are rather confusing, which one should I order?

Thanks in advance!
