Alternative Steering Wheels?

Further to my recent threads about using the EPS from a Prius in my project car, I'm now trying to work out what other steering wheels will fit the column.

Several companies advertise Prius steering wheel hubs, but these are for cars fitted with airbags - which mine isn't, so I need an alternative that has the correct spline but no airbag.

The actual wheel I intend to use is a Momo with 6 bolts on a 70mm PCD, and this fitment seems to be common on a lot of the hubs used on Toyotas too. But I don't know which model to ask for!
