'33 Steering Wheel Hub?

[esff32]

Anyone know what hub is used on the hotrod steering column? I have a Sparco racing steering wheel and when ordering a hub on their website, it asks for type/model of vehicle. The reason for not using the FF one is the horn button does not fit inside the hub. Any help would be great. Thanks fellas.

Thanks Erik, I spoke to someone at NRG today and they said the hub for the ididit columns is the SRK-170H.
